It's correct, but in bias circuit use 1k2 instead 680R

B500 4 pair Darlington output stage

It's working....😀 very nice....
Thanks again Mr. Mile....
BTW what would be the max power could achieved with 4 pair of darlington output stage with +/-78VDC rail voltage?

Nice work, with +/-78VDC output will be about 50v RMS or 650W/4R.

congratulations. excellent work. It's really impressive professional finish B-500 amp.
A query such heat sinks are computadpras.
PS: Please could you upload the pcb in Sprin Layout.

yes , working very nice

Hello LIEM POO...Greetings ..🙂 I have repositioned the tranies of this PCB to adopt to my Heat sink... Kindly check for any errors.

Hello Sir APEX... hope you can also give suggestion for the parts if something need to be improved. If all is well ... I can start making the PCB for this.

Many thanks to ALL
Best Regards
