500W PA amplifier with Limiter

Yes Sir.. I like your system.. have you tested the pcb and how about the sound... can you send me the pcb layout in pdf file..? thanks
I will test the lay in the near future. No pcb layout in pdf, if you need I can do.

Please share the schematic Sir.. I think your pcb and component litle difrent compare with B500.. how about the max voltage for this amp..?
The scheme is identical to the apex b500, just add a resistor to set the quiescent current output stage, and used an opto limiter АОР124Б. Power supply in the may version of the +-35V .
irwanks B500 with 2 pairs output transistor only for homeaudio
which the resistor used to regulate the bias current?

Yes mr Irwanks.. ..mje 15033 and mje 15032 easy to find in malaysia.... How in Bandar lampung easy to find overthere.? Next time if I back to Bandar lampung I want to make saound system project...
I hope you can help me and join together.. what do you think mr Irwank...?
It is hard to find mje 15033 and 15032 in bandarlampung. I use A1837 and C4793 instead of mje 15033 and mje 15032. What kind of project, sir? sorry I only can help soldering if i have time, i can't help much.
 
Today launched its lay APEX, works well, sound is clear, deep, sounding pleased. Just heat up much before the output stage transistors, had to put a small radiator.
The amplifier was tested by a weak power supply capacity was not high, the limiter is not plugged, it is necessary to recalculate it for this amp.
