early wireless and gramophones in WW1. Richard gave
us a high quality display of equipment along with demonstrations of early morse transmission and reception. An
auction of donated items was also held to clear stock.
Derek Wright gave an interesting presentation at our August meeting on his experiences with the ABC 1960’s coverage of a TV link using the Carnarvon OTC satellite with
the UK. Norbert Tourney also gave a detailed “Items of

Rodney House presented a well-received talk on Historical
Records (famous people on records) at our October meeting. An auction of donated items was also held.
Our November Social event, held on 25 November, 2014
was held at the Clubhouse. Thanks are due to those
members who organized and brought the food and drinks
to make this a successful end to our 2014 Club Year.
Thank you to those members who collected and stored
items donated to the Club, until they could be auctioned.
Special mention to Tony Smith and Andrew Wakeman.
Our Club membership currently stands at 52, (plus or minus!). This is a healthy number. Thanks to those, especially Tony Smith, who work hard to increase membership.

Andrew Wakeman

Andrew
Some of our history from 1996! Can you
identify any of those present?
Sad Passing of Garry Stoyles.
Garry Stoyles passed away suddenly on Thursday 3rd
July 2014 aged 54.
Garry was keen member and a regular participant at
the Vintage Wireless and Gramophone Club meetings
where he had made many good friends.
Garry was a very talented musician who had a huge
thirst for knowledge and a love for life.
Garry will be missed by all who knew him.
By Andrew Wakeman, Club Secretary.
Need a rare valve? These were seen at the
Esperence Museum, but maybe not for sale!
Remember these adverts?!
$18 must have gone a lot further
in 1937 than it does today! And
radios and gramophones were
relatively more expensive in
those days too! No wonder we
often made out own!

Restoration of a Philips 161b
- 1955 Vintage Mantle Radio.
Reg Gauci
Around the early part of October 2006, my brother
offered me our grandmother's 50 year old mantle
radio that he had in his shed. He had inherited it
around the end of 1975 after she died and had
used it for several years. When the radio broke
down, he just kept it for sentimental reasons. There
it sat on the shelves of his various sheds through
several house moves.
As expected, over 30 years of grime and dust from
my brothers sheds had accumulated inside the unit. I
started by pulling the chassis and inspecting the wiring. The dial cord had long since broken but there
was still sufficient in place for me do quick diagram in
preparation for the replacement.
I thought that Grandmas radio might make an interesting project and see if it could be resurrected to
something like its former glory.
When she was alive, the volume knob had broken
and, as the original type was not available even then,
I had obtained a knob from Philips that was used in a
similar set made at about the same time as the 161b.
18
It was not the original shape but at least it fitted the
volume control shaft.
The underneath was quiet clean and some of the
more susceptible capacitors and resistors had been
changed many years before - probably by me when I
worked for Philips in the 1970s. The wiring seemed
sound and there was no sign of corrosion.
I started by removing the speaker and dial assembly
to reveal the tone and bandswitch mechanism.
These plastic gears (especially the tone gear) had
deteriorated badly over the years with the central bits
not gripping the shaft. More on these items later.
With the speaker and dial assembly disassembled, I
removed the valves and gave them a wash in warm
soapy water. This caused the valve numbers to
disappear so I re-marked all of them using a felt pen
They were then carefully packed away and left to
dry. The dial lamp was 'long gone'. As it happened, I
had about a half a box of the appropriate lamps that
had been sitting in one of my old electronic service
toolboxes for over 30 years.
The chassis was cleaned using a paint brush and
methylated spirit - it came up a treat. A bit of lubricant spray into the valve sockets and it was ready
for the BIG fix.
19
The dial cord was re-strung and a test was conducted
to see if hot glue would secure the band-switch and
tone gears to their respective shafts. This was not
successful as the hot glue broke away from the shaft
after a few turns. Even more on this later.
Still with the valves removed, I then plugged the radio
into the mains for its initial 'smoke test'. Nothing happened so I got my trusty multimeter out and did a bit
of checking around the mains power area and the
transformer secondary.
All was as it should be. I then plugged the rectifier
valve in and checked that the HT supply was OK. I
suspected that the dual high voltage filter capacitor
had deteriorated during its prolonged period of inactiv-
speaker worked well with no vibrations and had
the 'tone' that these units were famous for.
I then switched to the shortwave band - only the
more expensive Philips mantle sets had shortwave
- the switch had some corrosion on the contacts
and crackled badly when jiggled. A quick spray with
the appropriate lubricant (and a shot in the volume
and tone pots) settled the old girl's noisiness. With a
length of wire attached to the aerial terminal, shortwave stations sprang up all over the dial.
I hot glued a strip of plastic over the mains connections and blobbed a bit on the switch pot contacts. When I find some appropriately coloured
three core flex, I will replace the original 2 core
(no earth) and add a margin of safety by earthing
the chassis.
ity, so the twin capacitor was replace by two individual
units that were each of about double the value of the
originals. I think that the 6V4 rectifier can easily cope
with these increased values and the power smoothing
will be better than when the radio was new.
The electrical bits now sorted and the unit working well, I
decided to try to duplicate the remaining front knob and
create a facsimile to replace the incorrect one that I had
I then popped in all of the other valves and 'away
sourced more than thirty
she went'! Turning the dial mechanism I was
greeted by a burst of local AM stations. The

useless.
This mould worked well and the knob was completed by
pouring the mixture of epoxy and hardener into it and
shoving the shaft and upper part of a sacrificial knob
that I had purchased from Altronics into the epoxy and
then let the whole thing harden for a day.
On the label was the name of the company that has supplied it so I phoned them and they said that they could
still supply the product - a minimum of 1Ltr. I hopped into
my car and drove to the warehouse in Osborne Pak and
forked out some $35.00 - all this for a knob
The excitement was mounting so, early the next

firmly gripped by the epoxy. The only problem was
that the epoxy had taken on some the colour of the
plasticine. In the end this colouring did not detract
from but may indeed have enhanced the look of the
knob.
A bit of time was required to grind the shaft of the new
knob so that it would slide over the pot shaft. All knobs
morning (still in my jammies) I tried making a mould of
the existing good knob with plaster of Parris. This was
a dismal failure as little bubbles formed where the
plaster touched the knob sides and no amount of
bashing of the mixture onto the bench would dislodge
them. This resulted in a knob that was quite grainy to
the touch and not smooth like the original.

are now for metric shafts and are substantially
21
smaller than the ones used back in 1955 Australian
Radios. I had to carefully grind out the sleeve, bit by
bit, until it slid securely over the control shaft.
This completed, I turned my mind to the cabinet. I removed the front and gave the whole case a good
scrubbing inside and out with soap and warm water.
Once dried, I removed the Philips badge, masked the
plastic grille and sprayed the bits that were originally
gold with a couple of coats of uick drying gold paint.
The burgundy part of the cabinet had many marks and
light scratches and looked somewhat dull. I got the REPO liquid wax car wax out and gave it a good going
over. The cabinet sparkled as if it was new.
The freshly painted front and grille section were
now reassembled and the rejuvenated cabinet
began to take shape. I finally sorted the knob
gears out by melting bits of wire into the central
part that contacted the flat part of the shaft.
This had the result of a much sturdier friction bond
and less likelihood of the gear 'twisting' off the
the front of the knobs. Nevertheless it looks good
and works well.

The Telefunken Nauen 330 WLMK
were deported from their homes put into cattle trucks and
then, without any belongings, dumped in Westphalia.
Mum stated it was essential to get a radio, to be informed
of what was going on, during these trying times. The then
already fourteen years old Nauen was the only one she
could find for the price she could afford.
In 1933 “RCA” the company who
held the world patent on
“superheterodyne receivers”
(commonly called super) relaxed
their stronghold and sold licences
for a fair price.
Norbert Tourney
Telefunken took out the licence and designed their first
superhet. The motive for the Art Deco Bakelite case was
Telefunken’s well known overseas short wave radio sta-
While we were living at that small place in an old farmhouse, the radio was the only piece of treasured luxury
we had. Dad was an enthusiastic short wave listener,
and because he speaks Russian and French fluently he
always informed us about the international news, which
didn’t always coincide with the local news.
I was always fascinated, especially when dad used the
landlord’s telephone line as his short wave antenna. Because on short wave the radio was a TRF it meant we
heard the telephone ringing and the full phone conversation loud and clear. The first time it happened mum was
scared out of her wits and had an almighty argument with
dad. Later on she was quite happy to listen in, with volume right down.
tion at Nauen near Berlin. The case very well resembles
the building of the Nauen transmitter.
As it was common for the era it became an autodyne
(self oscillating mixer). Rather than sticking with standard
design principles, Telefunken used an incredibly complex
coil arrangement, two different Ifs, one for long wave and
one for medium wave.
To make the set truly interesting, when the set was
switched to short wave it became a TRF receiver with
tuned RF stage. The complexity of the coil assemblies is
breathtaking. The audio amp doubles up as the reactive
detector. From the service men point of view an unprecedented nightmare.
The design was less than successful and the set was
christened “die pfeifende Johanna” in English “the whistling Jo-Ann”, because of the facts that this set whistles
nicely between stations.
My acquaintance with the Telefunken Nauen happened
shortly after my birth. My family members are displaced
people from the former German state of Silesia, who
22
After a while we moved to Paderborn, because dad
found a job with a car manufacturer. The radio went with
us to serve another two years. Sometime after my eights
birthday the radio stopped working and mum bought a
new one.
Dad had built us a puppet theatre and the radio doubled
up as a pa system with the help of a microphone he had
scrounged up somewhere. Because the audio section
kept on working it doubled up as an intercom, as well.
Sometime after my twelves birthday when the radio was
supposed to be dumped, I became the custodian of the
Nauen. I spend untold hours trying to make it work.
During my apprenticeship as a radio and TV mechanic I
found out the two RF tubes had zero emission.
23
During the period 1962 to 1972 I could not find any of
these tubes anywhere, so it remained unfixed.
In 1973 prior to coming to Australia I sold the set together
with other interesting radios. I always felt I shouldn’t have
sold it. After I discovered eBay it was possible to search
for an identical one. .
To my horror, since 1972 the Telefunken Nauens have
become one of the most sought after radios. Every European collector wants one and the price has gone through
the roof.
The first one that turned up, in very original condition,
sold for an amount I couldn’t afford. That kept on happening. Finally I managed to get one, top case, original
knobs but no tubes and odd ball modifications
The “Enigma Machine”
Cryptanalysis of the Enigma enabled the western Allies
in World War II to read substantial amounts of secret
Morse-coded radio communications of the Axis powers
that had been enciphered
using Enigma machines.
This yielded military intelligence which, along with
that from other decrypted
Axis radio and teleprinter
transmissions, was given
the codename Ultra. This
was considered by western Supreme Allied Commander Dwight D. Eisenhower to have been
"decisive" to the Allied
victory.
Well before the radio turned up I had purchased a full set
of working tubes. So I wasn’t worried about the missing
tubes. However when the radio turned up and I examined
it all tubes and sockets had been replaced with ex WWll The Enigma machines were a family of portable cipher
microwave tubes, most probably from a discarded radar machines with rotor scramblers. Good operating procedures, properly enforced, would have made the cipher

unbreakable. However, most of the German armed and
secret services and civilian agencies that used Enigma
I had never heard of, or seen a radio rebuilt with five
1000 Mega Hertz microwave tubes. The job was done in employed poor procedures and it was these poor operata very unprofessional, very poor fashion. Of course it did- ing procedures that allowed the Enigma machines to be

n’t work and most probably never did.
I was determined this time I would have a Telefunken
Nauen that worked. A ground up complete rebuilt was
necessary. Doing a little research I found Telefunken had
upgraded the Nauen in 1935. This time it is a much more
conventional circuit, with commonly available tubes. They
upgraded it again in 1936 and 1938. The 1938 one used
common “P” base tubes, known as the red tubes.
I decided to rebuild it as a 1938 Telefunken Nauen, because I’ve got plenty of components from that period as
well as a full set of brand new tubes and their sockets.
The rebuilt took quite a few weekends, and was done in a
fashion which makes it look like original. However it is no
longer the “whistling Jo-Ann”, in actual facts it performs
like a typical 1938 radio.
I would have loved a stock original one, with original
tubes and the authentic whistle between the stations,
unfortunately the Telefunken Nauen has followed the
same pattern as our AWA Empire State radios, so a
stock original one will remain a dream.
Norbert Torney

The German plugboard-equipped Enigma became the
Third Reich's principal crypto-system. It was broken by
the Polish General Staff's Cipher Bureau in December
1932—with the aid of French-supplied intelligence material that had been obtained from a German spy. Shortly
before the outbreak of World War II, the Polish Cipher
Bureau initiated the French and British into its Enigmabreaking techniques and technology at a conference held
in Warsaw.
From this beginning, the British Government Code and
Cypher School (GC&CS) at Bletchley Park built up an
extensive cryptanalytic facility. Initially, the decryption
was mainly of Luftwaffe and a few Army messages, as
the Kriegsmarine (German navy) employed much more
secure procedures for using Enigma.
Alan Turing, a Cambridge University mathematician and
logician, provided much of the original thinking that led to
the design of the cryptanalytical Bombe machines and
the eventual breaking of naval Enigma.
However, the German Navy introduced an Enigma version with a fourth rotor for its U-boats resulting in a prolonged period when these messages could not be decrypted. With the capture of relevant cipher keys and the
use of much faster US Navy Bombes, regular, rapid reading of U-boat messages resumed. (thanks to Wikipedia

be a TRF.
“Little Maestro”
Off with the back!
Tony Smith
At a recent Club auction I fell in love with a little
wooden cabinet radio. It seemed to me that it would
be the ideal little set to be a bed-side radio. I had seen
the name Maestro before and looked forward to getting the it going,
The set's dial indicated both Medium wave and Long
There were the valves, all three of them! Lets check! a
6U8 (never heard if it) a 6AQ5 and a 6X4 rectifier.
This set was certainly a TRF as there were no IF
transformers and researching the 6U8 indicated that it
was a RF pentode and a triode all in one.
Only one thing for it - out of the cabinet and try to draw out
the circuit.
Once out of the cabinet Glory Be! There was another
valve tucked in behind the transformer, this other valve
also being a 6AQ5. Upon inspection under the chassis
would you believe that this additional valve was in a
blank socket and not even connected to anything! How
come the valve was left there?
What was it for? A spare?

wave. With three knobs, one the tuning, and one the volume and on-off switch, the other must be a band change
switch, or so I thought.
Turning the set on there were immediately some signals
around the dial. What was the other knob? It certainly
was not a wave change, but turning it varied the volume,
Underside of chassis view.
There was only the one set of tuning coils so the set
must have been sold as purely a medium band receiver. I was sure the set had not been altered as all
the wiring, components and hardware were certainly
commercial.
The tuning capacitor was a two gang unit but only one
section was in use. This led me to think that the basic
chassis could have been originally a superhet. The
manufacturers perhaps put this out as a cheaper little
set using the basic components and where selectivity
and sensitivity were not paramount.
View of valves and 2-gang tuning capacitor.
24
The pentode section of the 6U8 was a reaction grid-leak
detector followed by the triode section used as an audio
amplifier. The 6AQ5 was the conventional audio output.
25
The reaction control was a potentiometer wired to vary
the screen voltage of the detector. Another interesting
feature of the circuit was the inclusion of a small heavy
duty resistor of less than 2 ohms in the heater supply to
the valves. Could it be as a protection for serious power
fluctuations?

Recently I went to Jaycar electronics
for some radio rations. A note was
given to me by the staff. It was a note
from an elderly gentleman who wanted
to give away a valve radio.
Fred Franklin
It more or less sort of works he told me.
"I have changed

and got it from
the shed. The

Music Masters console radio's cabinet had been painted flat
white, speaker cloth and all.
I hit the roof and came down screaming about the beauty of
timber and that the only place for white paint is on ceilings
and the middle of roads. He said that I was a slave to history
and that the radio could be further enhanced with some pictures of palm trees.
I searched the AORSM manuals for a circuit and noticed
that the valve line up is 6J8GA mixer, 6U7G IF amplifier,
6SQ7GT detector and pre-amplifier, 6V6 output and a 5Y3
full wave rectifier.
The circuit is fairly basic and I appreciate this in anything
but the valves are a little unusual in a domestic radio.
The first thing to do was to remove valves that were incorrect. One was an EL33 (MM use a 6V6) and an ECH33
(MM use a 6J8GA). After removing the chassis I tipped it
upside down and noticed that the owner had replaced the
original electrolytic capacitors with some younger ones.
These I replaced
with current ones
from the valve
bank. The dry
capacitors had
been correctly
replaced with the
current types
from Jaycar.
However, rather
than remove the
old parts completely he cut the
old part's body away from the wires and soldered the new
parts to these wires. I will remove the old wires and reinstall the parts. Every joint in a conductor is a weakness in
it.

The Story of the 8-Track Cartridge
Richard Rennie
ROMA E 8-114ACK
What is a Cartridge?
Definition of Cartridge: A container enclosing
recording tape usually in the form of an endless loop and on a single hub.
The Echo-Matic (1952)
The Echo-Matic tape cartridge was designed in
1952 by Bernard Cousino of Toledo, Ohio. It
had a single reel carrying a continuous loop of
standard 1/4 inch plastic oxide-coated recording tape running at 3 3/4 inches/second.
Program starts and stops were signalled either
by a conductive foil splice or sub-audible tones.
The tape was pulled from the center of the reel,
passed across the opening at the end of the cartridge and wound back onto the outside
of the same reel. The spool itself was freewheeling and the tape was driven only by
tension from the capstan.
These are not cartridges:
Talking book for the blind (1950s)
These talking books used 2-track magnetic
tape on a single hub - but not an endless tape.
The Fidelipac (1954)
George Eash, also of Toledo, an inventor who
had rented space in Cousino's building in the
1950s, later revised Cousino's design, receiving
a patent in January 1957 and marketed it under the name Fidelipac. These cartridges were
used in radio stations (broadcast cartridges)
from 1959—on, to program commercials and
single song hits.
Tefifon (1950-1962)
The Tefifon used an endless tape in a single
hub container, but the tape was microgroove, not magnetic recordings.
Earl Muntz
The Muntz Car Company (1950 - 1954) was
created in Glendale, California by Earl
"Madman" Muntz, a well known local used car
dealer and electronics retailer. He produced the
"Muntz Jet". The car, a sports coupe, was
manufactured in Chicago, with aluminum body
panels and a removable fiberglass top. It was in
existence from 1950 to 1954.

Lear Stereo 8 (1966 - 1980s)
Munz Stereo-pak (1962 - 1970)
Earl "Madman" Muntz saw a potential in broadcast carts for an automobile music tape system,
and in 1962 introduced his "Stereo-Pak 4-Track
Stereo Tape Cartridge System" and prerecorded
tapes. He licensed popular music albums from the
major record companies and duplicated them on
these 4-track cartridges.
The Stereo-Pak cartridge had four monaural or
two pairs of stereo tracks. To switch back and
forth between the program tracks, a manual lever
is engaged, which physically moved the head up
and down mechanically. The Stereo-Pak did not
switch tracks automatically, unlike the later Stereo 8 cartridges.
Playtape (1966 - 1969)
PlayTape was an audiotape format and playback
system introduced in 1966 by Frank Stanton. It
was a portable two-track system, and was
launched to compete with existing 4-track cartridge technology. A PlayTape cartridge used
small 1/8" tape. The cartridges played anywhere
from eight to 24 minutes, and were self rewinding. Because of its portability, PlayTape was an
almost instant success, and by 1968 over 3,000
artists were published in this format.
After taking a ride with Muntz in a 4-track playeroutfitted car, Bill Lear, maker of the Lear Jet,
modified the 4-track technology to create the Stereo 8 cartridge, widely known as the 8-track.
Most notably, eight tracks were squeezed onto the
same 1/4" tape, reducing potential audio quality,
but allowing twice as much music to be put onto
the same length of tape. The pinch roller was also
an integral part of the 8-track cartridge, although
many early rubber rollers would suffer from deterioration because the rubber had not been fully
cured.
While some of Lear's improvements over the 4track are a bit dubious, his real refinements were
in the area of marketing. All 1966 Ford cars offered a factory installed in-dash 8-track player.
In the 1967 model year, Chrysler and GM offered the same.
Q8 Quadraphonic (1970 -)
A quadraphonic version of the 8-track format
was announced by RCA in April 1970. It was
first known as Quad-8, then later changed to
just Q8.
The End of The Track
At the time of PlayTape's launch, vinyl records
reigned supreme, and Earl Muntz's Stereo-Pak
(based on the broadcast "Fidelipac" cartridge system) was also a popular sound delivery system.
29
Eight-track tapes were with us for quite a long
time. 8-track was the preeminent portable and
car audio format of the 1970s. Record clubs
like Columbia House offered 8-track tapes,
well into the 1980s.

dio coupling and treble cut across the output transformer).
The set was "dead".
—————————————————————————
It seemed that a previous owner had set to work and
changed all the capacitors to modern ones, and had apparantly also changed some resistors, as there were a
couple of resistors obviously of a more recent make.
The valves were checked first, and then with a signal
generator a signal was introduced to the IF stage. This
proved that the set was operative from there on.
Finger on the converter grid brought in the locals,
but the selectivity was poor - like a simple crystal
set!
The first diagnose was - is the converter oscillating as it
should?
Turning over the set and looking carefully at all the components around the converter and the continuity of the
oscillator coil it seemed that everything was in order. As
a safety measure the value of each component was
checked against the circuit diagram to make sure. Then
- it was obvious that the feed resistor suppling HT to the
oscillator was incorrect!
The circuit called for a .03 meg resistor, but in place
was a .3 meg. This presumeably meant that the oscillator simply did not work due to a lack of voltage. Replacing the incorrect resistor with the right value immediately brought the set to life.
A simple error by the previous enthusiast had brought
the whole set to a standstill. Looking at the colour
code it was clear that the enthusiast must have mistaken a yellow dot for an orange dot and hence the
incorrect part went in.
TIP - Always check new and old resistors with your ohmmeter when replacing ones in a set. If you are installing
secondhand parts note that whilst the colour code may

Philips 2516
Looking back at
the story of the
Philips 2516
(Radiogram June
2014) the resultant quality of the
reproduction through the diaphram speaker originally
chosen to show off the set was not good. Such speakers
have a poor performance and this one was not doing
justice to the set.
Referring back to the restoration of the 1929 PILOT
(Radiogram Jan.2014) what had been forgotten was that
when the original set was picked up from the shed there
came with it an extention speaker and it's cabinet, in a
very bad way.
Flash! Why not restore the cabinet and try to connect the speaker to the Philips. Considering that
there was an 8" speaker fitted in the cabinet it
surely would be better than the old horn speaker.
After refurbishing the cabinet it was time to correctly
match the speaker's voice coil to the impedance of the
output of the set.
Trying several different transformers it turned out that
the best performance came with the installation of a
"line" tranformer, 600 ohms to 3 ohms.
The resultant performance of the set and speaker is
quite remarkable, considering the age and design of the
set, and people not familiar with such old sets are quite
amazed at the sound.

DANGEROUS
LITTLE RADIOS
Fred Franklin
Thankyou Tony Smith for
sharing your interesting
Phillips 2516 radio with
us. Radio-gram, June
2014.
O
You noted that one setting for the aerial connection connects the aerial to
the 240 volt mains via two capacitors, an aerial type that
you and I do not recommend.
I have noticed from time to time some vintage radios have
their aerial terminal connected to the 240 volts mains via a
high voltage rated 100pf -200pf capacitor.
WANTED
One 6 inch electrodynamic speaker.
Contact Fred Franklin, 12 Dulverton Ct, Karama,
Darwin, NT 0812. Phone 0428 883 195.
Before plugging the radio into the mains inspect your
radio and/or its circuit diagram for this deadly connection and remove this connection as a priority.
NOTICE
Back in those days some people mused about using the
power lines as an aerial due to their length. Others used the
idea to remove the inconvenience and/or untidiness of a
long piece of wire as an aerial. This is extremely dangerous and not to be thought of at all.
One of our Club members, David Fisher, recently had a number of valuable items stolen.
Please refer to our Website for details, and contact one of our Club Committee if you have any
information on the stolen items. (Editor).
This was a selling point for the Mullard 651 and the similar
Philips 101, a large Bakelite mantel radio. I have seen this
connection in some other radios as well. These two radios
are identical.
They told me I had Type O blood, but it was a typo!
If the connection does not electrocute you or the user, then a
failure of the capacitor will destroy the radio and/or you as
the 240 volt mains travels throughout the electronics of the
radio and blows it up.
I didn't like my beard at first, but then it grew on me.
When you get a bladder infection urine trouble!
Broken pencils are pointless!
The first rule of work (and hobby) safety is; if it looks dangerous it is dangerous. Fix it before it fixes you.
