Yeah, I was surprised at that. But they haven't vented and they still test good. Two of the MOSFETs (IGBTs?) have blown up, though.
I was thinking of temporatily connecting them in a tubed power amp and seeing how they sound.
On a related track, has anyone tried using supercaps in a solid state amp? You'd need a bunch in series, and it would be expensive, but you could get farads of capacitance fairly easily. I've seen individual caps rated at 2.7V and 3000F. So if you need, say, 100 volts, that would be 40 in series, with equalizers (which are available in kits). 40 would give you 75 Farads! The thing might run for hours or days after shut-off. You'd probably need to incorporate a discharge circuit. But it would be interesting, if expensive, to see what it sounds like.
