Ok. So she's not much of a looker, but I brought her home anyway. Oh... and I have this amp I'm gonna need some help with.
Got this thing a few days ago, but you know how life gets in the way sometimes. Bastard. Now I'm free for a minute and wanted to ask some Q's and post some pics. I'm no tech, but the dimbulb on my neck told me I should power this thing up with a DBT and it passed. Checked DC offset. Got -9.4 mv on the right and -3.3 on the left. Seems good to me. Want to check bias, but I'm not sure where R38 is located. Guess that would be my first question. Next I am curious about the outputs. Seems a couple have been changed on the left output and are a different pn than the rest. Is this bad? Last big Q for now. I want to rehab and upgrade this thing all the way, but can only afford to do it a step at a time. What would be a list in order of priority. Obviously check offset and bias and I have the dc protect board I plan on doing tonight or tomorrow. Well, Here she is.....

No need to be honest here.
