Dear Mr. Mile S...
I have a problem now on my second built SR200 amp, I can not set bias for one channel, the other one is just fine. Both of them sound good also, but they have difference heat sink temperature (because of bias setting I guess), and the one that I can set bias is sound better that the other one.
I already changed DB139, 2sc4793/2sa1837. I have check all small transistor (bc's) I think they are OK...
I need you advice.
Thank you so much..
Best Regards..
