Oddly enough, I'm finding yellow mylars with the same greenie lead disease. One flex, and the lead is gone. I assume you're talking about yellow caps from the early '60s? Not the new ones we're all using now. Jeff |

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. Jeff |
