Service manual direct download: dox.abv.bg/download?id=44a915751c Hi. I try to repair this amp from a long time. All four mosfet 2SK1529/2SJ200 was short, R521/621 and R520/R620 was open. At this moment i remove all final transistor 2SK1529/2SJ200 i put lmp 75watts all relay close contacts but here is anather problem. On Q509/510 and Q609/610 i have 45v on BEC. I remove Q509/510 and Q609/610 from mainboar, and now i have 45V only on BE, collectors are 0v. But on service manual on emitters i must have 2.4v.... I don't have any short on all elements. Can you tell me what can i try, please.

It sounds to me like you are finding a problem with both channels still. If you need me to help you locate the problem I would have to start from scratch. Jumping in to where you are now would be like hunting for a needle. So this would mean I would need you to put all good parts back in and we can start testing from there.. Let me know what you want to do.
skydronelink: Thank you I advance

wolfman: Always the same sarkasm Kurt that's why I never checked in until now. I knew you wouldn't give me a cheerful answer so let you hang for a while. Removed the last part you probably are a decent guy Eye to Eye.
