WAØTTN Collins S

WAØTTN Collins S-Line Station
This is a fully functional Collins S-Line station that has been in active use since I bought it in 2006. In
other words, it has not been sitting in storage, nor collecting dust on a shelf. I’ve done extensive work on
cleaning what little dust and grime out when I received them, replaced all of the recommended
capacitors (with exceptions noted below), and have maintained the units in excellent operating
condition, including tube replacements when rarely needed.

No previous history documentation, however the set was in excellent condition when acquired
in early 2006.
Lovingly cleaned, recapped, and maintained by yours truly.
All cables included as supplied to me. New, not original. All are labeled clearly for easy hook-up.
Complete set of reprinted manuals, including full-size fold-out schematics, conveniently tabbed
in a three-ring binder.
Approximately 120 watts on 80/75, 40, and 20 meters, approximately 70 watts on 15 and 10
meters.
All equipment is very clean and has never been in a smoking environment. Original luster is very
well maintained.
Control knob lines have been retouched with brilliant Titanium White for that original pizzazz.
Spun aluminum knob inserts are in perfect unmarred condition.
Meter faces are clean and “factory” sharp. Meter glasses are clear as crystal with no fogging or
blemishes.
