Alex I have tested pcb made by you with this layout couple of year back and driver transistor is mounted on heatsink, mje340 and mje350 barely get warm. I did tested with 80VDC supply. one can put heatsink to be safe. nice pcb you made very compact.

Hi to all I have a question about sr 200.I made the sanken version pcb by Alex MM with one pair of 1943 5200 just for testing and with the zobel network that was included on pcb I couldn’t adjust the bias it stayed at 4.5 ma ,but without it everything was ok the amp worked to my ears very well . I also include the two 1n4007 diodes was missing from the pcb .And I must say that i don’t have an oscilloscope to make more measurements .Is that normal or not?
Thanks!!
Thanks!!
