>Resistor off of grid of 47, resistor on the bottom of the volume control,
Your looking @ abt 250K to 500K 1/2w it's supplying the bias for the 47 tube. Value not very critical.
>value of cap between the 2 8 mike 'lytics,
1mfd 630v mylar it's there to tune the field coil to 60cy.
>why is there a 500K resistor in parallel with the 130Ω and 400Ω sections of the candolm
Not sure but because of the other resistors it's pretty much invisible because of it's high value.
>value of the cap to ground near the cathode of the 56
Small value as it's bypassing rf out of the audio signal 100-200mmfd.

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!
