To answer your questions sir, I would take a guess at abt 100 ohms or less. You may be able to install the diode and not have to add a series resistor. Just check your B+ to see if it's @ 120vdc under load. Note the diagram has the diode drawn backwards.[Image: https://philcoradio.com/phorum/images/sm...on_eek.gif] The band goes to that white loop thingy (22 ohm resistor).[Image: https://philcoradio.com/phorum/images/sm...wisted.gif] The trick is that the filter caps are going to charge up before the the tubes get hot to provide a load for the B+. This means that for a few seconds after the set is turned on the filters may be seeing 160-170vdc till the tube warm.
The .0047 are fine to replace the line bypass caps.

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.

Now I think I've got it!
