KISS. Wire a 60w light globe in series, turn it on, let it sit for a
few hours. Filaments OFF for this test.

Havent used a variac for this for years - reason - its the switch on
current surge thats going to kill old electros, and the variac has no
current limiting whereas the light bulb does. You will see a brief
"Flash" as the caps charge up, then maybe a dull glow, eventually, no
light at all.

Given that the caps used were / are modern, and of good quality to
start with, the KISS method works well.

Oh, BTW - when all this is done, apply full mains power, let the tube
filaments soak for a few hours lest they have gone gassy.
