i replace the resistors with half watt resistor but same problem. in both pcbs those resistors burned. i checked the transistors but transitors ok.
the amp is working in this condition,
I am sorry because you are facing this problem in both PCBs, but I want you to double check that the PCBs you have made is a clone of the LAST one I have posted, not the first, as you remember there was a problem.
Also check your solder, transistors directions, Diodes every thing
Let me know results please
