AVR2106 - 1 channel blown :-(
Hello,
I am working on same exact issue with AVR2106.
IT is a european model and the service manual look accurate (no zener, 2SB1647/2SD2560) Where are your zeners located ?
I have replaced so far 2 x power transistors, 1 x bias transistor, 4 x 0.22ohms & 2 x 4.7ohms. Got the parts from the 2 extra channels that I am not using - you might try that.
Amp powers up ok now, however sound is heavily distorted (it cracks) except at very very low volume.
I can measure that there is no bias (no voltage accross 0.22 resistors) however other components measure ok. Am I missing something ?
Good luck
