SERVICING IN THE FIELD
SAFETY GLASS REMOVAL
location, see "Tube Placement Chart".)
Remove 2 screws at bottom of picture tube holding trim.
Remove spring holding trim strip around picture tube. Remove 2 screws holding metal shell strap. Remove strap and
front glass.
FOCUS
The focus may be varied by connecting the lead from pin 4
of the picture tube to various voltage points. (For location,
see photo "Chassis-Top View".)
FUSE
HORIZONTAL OSCILLATOR FIELD ADJUSTMENTS
A fuse wire is used for filament protection. (For location,
see M4 in photo "Chassis Top View".)
Coarse adjustment of the Horizontal Hold is accomplished
by the proper setting of the Horizontal Frequency control.
(For location, see "Tube Placement Chart".)
FUSE DEVICE
A 5.6fi fusible resistor is used for low voltage power supply protection. (For location, see "Tube Placement Chart'.')
WIDTH
TUNER OSCILLATOR ADJUSTMENTS
The width may be varied by adjusting a metallic sleeve, located between the yoke and the picture tube neck, in or out
of the yoke.
To touch-up the VHF Oscillator, remove Channel Selector
and Fine Tuning knobs.
CENTERING
AGC
Centering is accomplished by 2 magnetic rings, located behind the yoke, on the neck of the picture tube.
The AGC may be varied by means of a Range Switch. (For

TUNER ALIGNMENT INSTRUCTIONS
PRE-ALIGNMENT INSTRUCTIONS FOR TUNER T100, T101
The high voltage lead should be securely taped and kept away from the chassis.
Allow a 20 minute warm-up period for the receiver and test equipment.

VHF RF AND MIXER ALIGNMENT
Set Range switch to "Normal".
Connect the negative lead of a 1. 5 volt bias supply to point <^> . Positive to chassis.
Detune the Mixer Plate coil by connecting a 10 to 20mmf capacitor across it.
Connect the synchronized sweep voltage from the sweep generator to the horizontal input of the oscilloscope for horizontal deflection.
The sweep generator output lead should be terminated with its characteristic impedance, usually 50 ohms.
Use only enough sweep generator output to provide a usable pattern on scope.
Use 10MC sweep unless otherwise noted.
Coils not containing adjustable cores are adjusted by expanding or compressing coil turns.
