All, I have an SA-7800 which arrived this weekend. I pulled the cover and did the initial inspection. Looks like a few burned resistors. From what I have read, I need to do a full test of each component on this unit. I did fire it up on a DBT, which might have not been the best approach, but the seller had it powered up for pictures, so I assumed if any damage was done, it was already there. I have voltage on the left side of the amp test points, but not the right. Burned components are on the right. Any advise on how to approach would be appreciated. This one is going to take some time.
