Depends on what your objective is. My observation is that many shops try to take a minimalist approach and find what is wrong and do just enough to get it working. Others that are enthusiasts rather than shops running with high overhead and economic constraints will "restore" rather than just get it running.
So you have to decide what you want...
Looking back over the OPs prior posts reveals that he has been here on AK asking about the same subject more than once. He has had exchanges with Ds in threads, at least.
Technetron, New York City. Will pay the value of one of the amps to get them restored, that’s how they will want to proceed. And this only if the two power boards on the bottom side of the amps aren’t roasted. If they are, they will never be stable, going into oscillation half an hour to an hour after they are turned on. Also, Sanken MT200 output based amps, NLA since 2018. So hoping those are still good.
It seems like most every one of this model I have seen have had issues. 504 and 508 amps seems to last but are a PITA to work on also when it comes to the main power caps
