Hi All
I have decided to finally attemt an amplifier design by myself after a few diy builds from various members here, Carlos (Destroyer) and Ostripper.
I designed and built a PCB which uses OStrippers output stage, and my own input stage, vas and thermal compensation.
Unfortunately when I power the amp through my test lamps, it seems I have some issue/s. R28 and R29 have an unsuspected 5v over them instead of millivolts and it cooks those resistors and blows a vas transistor or 2 as a result.
The design is attached below.
