Scored #5 on list: Pilot TV-37

[dtvmcdonald]

I only posted a "wanted" list a month or so ago ... and today I got
#5, a Pilot TV-37. This is the first auction I ever bid at (I was at the ETF
convention last month but did not bid, as I bought a set at the outside flea
market.) And it was only 12 mile from my house.

I and one other guy bid on it, selling for $40. I had to sit through
an hour of dishes and dolls, then 75 minutes of model trains until
they got to the electronics.

I had tested the line continuity and it was 115 ohms, which sounded
reasonable for such a set with two heater strings. So I hoped the
3KP4 at lead had a filament.

When I got home I got the Sam's and Rider's .. and they disagree
on the filament chain wiring! Both have all the current
going through the 3KP4, but one has it at one power line
end, the other in the middle. Apparently mine is in the
middle. Removing the tubes on either side shows continuity
for the 3KP4. I hope this is real!

This is not my front-line project ..
today is hopefully the day I get my first Atwater-Kent 44 working.
Its close! It gets audio out, and gets RF to the detector.
