As posted in another thread, I'm replacing .320a selenium rectifiers, the rating chart is here:

These are the diodes I intend to use, 3 amp 1000 v. Since diodes are cheap, might as well step up the rating a bit, just for good measure:

Since this set isn't working, I'd prefer to just get a resistor value and replace it. It's been recommended to me that I get a 25 watt resistor as opposed to a 2 watt, because of how hot they run. Does that sound right?
And what value resistor would I run? |
Just noticed your choice of diode - I'd go with the slower (and CHEAPER) 1N5408 diode. You don't need ultrafast diodes to replace a selenium rectifier.
Cheers,
