Re: Well, I figured out that 'Zpri' must mean 'resistance of the primary'...

Yes, that's right.  Your transformer will say, somewhere, '8K : 0, 4, 8Ω', or something.  I wasn't asking the power rating of the transformer, but about how much power your amp will produce into a given (say, 8Ω) load.  These are the most commonly available specs from which I can calculate how much AC voltage is on your primary.  This (multiplied by √2), added to the DC operating voltage, is the max that the capacitor will see.

Did you make this amp, or is it a boughten varmint?  If the former, what exact type of output transformer did you use?  If the latter, what brand/model/alphabetSoup is it?  I have some experience in this sort of research, we may be able to feegah.

What voltage rating caps were in there before?

Aloha,
