Philco 46-1209 Radio Can Capacitors
#6

Ditto what Phlogiston said.

I use 22uF 450V, or for 10uF same in series.
And, the main rule is: the only cap that should be close or the same value to the shown in the sch is the very first one after the rectifier tube. (22uF is just fine for 25uF, for instance).
The rest of the caps could be larger values without much effect. Of course if a cap is 20uF, one could use 47uF, but I would not recommend going to a 470uF or 1000uF (which I recently found in a couple of my radios that someone repaired in the past).

And, also, as Phlogiston mentioned, the very first cap should have a decent ripple rating and should not be a GP cap. If, of course, you cannot fit a film one in there.

Serialized caps of the working voltage close to the actual voltage do not require leakage equalization with resistors. If however the WV of the serialized caps is just over half of the actual voltage, then the resistors are recommended as otherwise a voltage across one cap could exceed the WV rating.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
