Giid leak voltage on Sears 101.557-1 chassis
#2

Hi Ed,
So your under winx's tower???
Check voltage on pin's 3 and 4 of the mixer tube if you have the 140v or so replace the 6J8. This is assuming that set has been serviced, tube sockets and tuning cap have been cleaned, and check for bent plates. Also check C-6 for proper tracking at the low end of the bc band, could be that it's adjusted so that it is out of the range of the oscillator ability to oscillate (too low).

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
