Hi people,
I made a amplifier following the Project 3A ( link is
When it worked, it is really nice, but last about one hour and it died. I replace some died power transistor, and test again. I try to increase the quiesent current by adjusting the pot VR1, and it broken again.
Can someone explain for me? What did it do like that?
I am looking forward hearing from people soon!!!
