I have Luxman L-85V amplifier with a non-working power amplifier section. The amp is in great condition otherwise and I know it works because I was able to switch the power amp section from another L-85V that I own and it worked. Looking at the PCBs they are a mess. One of them has transistor missing, a lot of parts were replaced, etc. So pretty much the only way to properly fix the amp is to completely rebuild the PCBs. My knowledge is limited but once I gather the replacement parts, I should be able to rebuild them (I did two successful recaps, built two amplifiers and did some other minor soldering work in the past). The problem is, if replacing all the missing and/or not working transistors would yield satisfactory results. Please keep in mind that most of the transistors are no longer in production so I would have to go with replacement ones. They may or may not change the sound.
Here are few pictures of the boards:
