37-630 Aux Audio
#4

Hi John,
> Does anyone see this as a possibility? 
No not so much.
I think what you are experiencing is leakage from the diode section over to high gain triode section. It's a fairly common thing on sets that use a 12AT6 or 12AV6. When you turn the volume all the way down you still the set playing a little
Would try a different 6Q7 and see if that helps. You could lower the value of 41 say to 220k or so but this will lower the volume of the radio a little.

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!
