Philco 71 restoration
#19

No problem. I'd check the plate and screen grid voltages on the rf amp, mixer, osc, and if amp. If all that looks good check the osc to hear if it is running. Next I'd break out the signal generator and tracer. Then you can hear where the signal is starting and stopping.

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 it!
