This is my first attempt at recommissioning a tube radio.
It was donated to me.
I read up on the process.
I understand that a Variac is recommended, but without being aware of the previous cap replacement, I elected to make a brief functionality check. A long wire antenna was connected, and the chassis grounded to a radiator. The radio powered up without issue, all five tubes' filaments lit up.
The audio was a buzzing in the background with a whine superimposed on it.
The audio was loudest at the 1700 kc end, decreasing at lower frequency. One station was clearly received at about 1000 kc, broadcasting the BBC World Service. I did not wait fot station identification, and unplugged the set to begin my physical inspection.
