I assume you're talking about yellow caps from the early '60s?

Not the new ones we're all using now.

Of course! I assume your talking about old power resistors
too :)

Waiting on the new 5 watt metal film resistors to correct the
power supply resistors. (replacing the sand ohm and candelohm
resistors.) Still need to pu the 9.1 V zener across the 3V4
(B+) and ground to protect the filaments from over voltage.


They came in today. Put hem in and oh boy, a radio that works like
new. Also, as pointed out by another tech, I moved the 9.1 V zener
from directly across the filament line to across the last 910 ohm
resistor in the series string. So it's only across the filaments on AC
power, not with the battery.
