If you want to build amp with 12 pairs o/p or more and classH, use crest pro 10001 schematic and clone output stage.
Crest Audio

@ apex

Sir if b500 will be bridged at 77+- vdc because. i have trafo 55 0 55 2000va and loaded with 4 ohms. i think i will end up burning my amp. i will have peak to peak voltage of 154 then try loses or voltage sag to 134vdc p-p. so the amp power would be 4489 watts at 4 ohms. if the power is continues the current 33.5A. if it is possible to do this way how many trannies needed? maybe need to used mjl4281 bec. have higher voltage rating than 2sc500.
pls. comment sir apex about this. thanks alot
