Leach Amp with 12,000uF Caps

[wigginjs]

I'm planning on using two Cornell-Dubilier computer grade 80V 12,000uF "Snap-In" caps for the power supply in my leach amp. This will power two channels and both channels with be driving 4ohm loads (nominal). Are these caps large enough? This amp is for home theater use and I'm not trying to reach extremely high volume levels. Also, will an 80VCT@6A torodial transformer work, or should I get an 80VCT@8A?

those are bigger than Dr Leach recommends so you should be just fine. If you're going to be driving harder loads, you'll probably want the 8A xformer.

Are you saying that a 4ohm load is hard enough to warrant the 8A transformer? Or than loads harder than 4ohm will need the 8A transformer?

I would go for the 8A. IMHO better safe than sorry . . .

Althou' there was a discussion once somewhere debating sizes of capacitors and transformers . . .

Sorry for being confusing, yeah, that's what I was suggesting. Although the leach amp does have current limiting so maybe you can't exercise more than the 6 amp anyway. Honestly, I imagine you'll be fine with either direction you go, but you might as well go with the 8A if you can.
