I have an M-50 that just won't cooperate.
It came to me in protection mode and upon initial inspection the right channel had been pretty badly fried. No real damage to the actual boards but many burnt resistors and such. I had already planed a full recap and decided to completely go through it in the process. In addition to all the resistors that I replaced a full recap on the unit was completed. Also on the right channel several transistors were open so basically all the right channel transistors got replaced. The outputs on the right were blown so all the outputs (both channels) were changed as well. I likely will get into listing all the details and specific transistors used etc but it still has issues that I'm not easily tracking down. Power up stays in protection and a couple resistors will light up (poof) as well...hard to troubleshoot because I can't safely power it up. DBT no help in that regard.
Also replaced the safety cap for safe measure.
Any ideas how to approach this...too much time in it to shelf it.
