so workhorse how much power do u think 12pairs of 2sc5200/1943 with rail voltage of +-140 and a 2 step driver will produce safetly

Keeping in view the rail sag if not more than 10Volts and losses in switch and transistors you can easily get 3KW @ 2ohms safe and easy on music + reactive loading.
Hi Mr. Mile
i have built B500 in bridge mode, i use 1800va transformer ,rail voltage 63+/- vdc(45ct45) . caps 6 x 10.000/100vdc. are those caps enaugh for this ?
Nice work, 6x10000uF is enaugh but this is minimum.
Regards
many thanks for your concern about my project mr. Mile

What protect circuit you use?

SUGGESTIONS ON B500 12 O/P PAIR BOARD
so here is the pcb with 12 o/p pairs ................ Miles can U plz check it ......... it does nt incorporate the protection transistor part ....... i will include it in the driver board ...... this pcb is just for checking and commenting purpose .......changes will be made as suggested....
Miles please take the lead and guide us.....

speaker wiring practice,
Speaker Wiring Info
suppose a 3kw @ 2r achieve,
according to this site paralleling 4 1kw @ 8r will give 4kw@2R load?
or in simple manner question as per 3kw@2R
how many 1000w @ 8R can this amp go?

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

Hi aman khalsa.
Thank you for test and share out put PCB ley out.

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
