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.
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,

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?

HI APEXAUDIO
greetings now that driver stage has 12 output pairs can vertex
3 step supply be used with this amplifier more power and effiency
thanking you

hey wat happened no body liked the pcb with 12 o/pairs .................. no comments no suggession wat happened................

sekhar,
where is the driver board?
is the output pcb final?better make component lay out,or else we will put all 5200's there(only joking)
did you use 5200/1943 instead mje's

another question is
can tlo step driver incorporate with this 12pair trannies?
workhorse said almost 3KW @ 2ohms
or upgrading to 12 pair need ir2117?
master's comment please?

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

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
