Zenith 6D029

At 500mmf it isn't going do much. It's either there to decouple a small amount signal from the plate of the 12SQ7 or to add some negative feedback between the two audio stages. This would increase the bass response of the amp stage. If you happen to have a small value cap laying around connect it in parallel with that 500mmf and hear what happens. Either it will cut some of the high frequency in the audio or get a little boost to the lows. Happy experimenting!!!
You know I'm a hacker at this!!!!
ps Good Job!

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!
