Hi Mircea
I had the boards made by a PCB manufacturer and built the amp. Set the idle current to 25ma per mosfet pair. Amp does not heat up. Played it the amp and the sound was distorted, and played for a few minutes and blew all the output fets. I however changed the Zener diodes to a different 12v zener as I cannot get the BZX2c12 zener. Would this cause the issue? Did you mach the mosfets? Please could you provide some guidance as to how you got the amp to work without any issues?
