Six 1940 Philco tv's giveaway

[dtvmcdonald]

I am referring to the coils, both oscillator and signal, in the tuner.

Yes, they really are that stable. Considering the stiffness, its not
surprising. I would not dare try to reset mine to all current channels.
On my TRK-12 only 3 and 4 match current channels. 2, 5, and 6 exist but are
neither 1939 nor postwar channel frequencies. All sweep quite well,
and all work perfectly if fed the proper signal (made by downconverting
a signal on a cable-only channel 34-40 MHz higher). But getting them
all to tune EXACTLY right was a chore ... I had to add a piece of
copper strip to one of the "loop" inductors. (There was a sticker with the
frequencies.) I put the 1939 channel
labels on when the set was being refinished.

The TT-5 was spot on as I got it.

To say it once again, the IF strips are marvels of good design and stability!
NOT CHEAP!

I would dispute anyone who says a 630 has a better picture than my TRK12,
at least with a good signal. Modern solid state B&W monitors, with some sort
of table-lookup gamma correction are the only way to get better.
