It's been discussed many times..but..

My 20 has the 1 1 1.5 and .13.

I used the 20a values os 2 2 1.5 and .47.

The original can was still in spec with one cap measuring .8 instead of 1.

Normally going over a bit makes for less hum..but others have mentioned higher voltages for this early power supply..that and the choke..field coil etc..it seems finely tuned.

Most who add higher values do 4 6 8 or 10.

I uses the 20a values good for 25-60 hz.

That said should I open the can ans replace the 2 with 1 etc...

Thoughts? Will using 20a values raise the voltages that much? Hum was minimal before rebuilding cap can. I have not tried it as speaker is getting reconed.
