Ok the short answer is to connect a clip lead to the chassis. Connect the other end to pin4 of the 41 tube. With the set on it should go quite. If not your issue is in the audio output stage. Next take your clip lead and connect it to the grid cap of the 75 tube. Same as before should go quite if not issue is in the 1st audio/det stage. Do the same w/the grid cap on the IF amp, Mixer and finally the ant lead. This will show which stage is noisy.
Turn the set on and to a station and then turn it off. From the monument you turn it off there is a brief monument that it's still playing. Still hear the noise?? If so it coming from the ac line.
Happy hunting

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!
