+1 on Casper at Stereo Rehab. He's not only a great tech but also a good, trustworthy guy. He can fix or upgrade just about anything, but his specialties are tube gear and as you say vintage Sony, especially the early stuff. He has a nice collection of Sony STR-6060 receivers, all of which he's rebuilt. One of them came from.... me.

I just saw that you finished the TA-N9 restoration , impressive! I'm still in the process. Did you convert the Amp to 220V, did you have to change something else by doing so? I was told that the Japanese SM is not helpful for the AEP version because the specs differ quite a bit.
oh I certainly don't want that, Nono! unfortunately I am not a tech, so just gathering all the necessary information and I am very glad to have found someone who has worked on them. Mine are original 220V versions, one has been partial restored inkl new old sk173/2sj54, but my tech doesn't want to proceed any further because he does not trust the Japanese SM with my AEP version. The changes you wrote about are only to the Power supply?
well, I am in Moscow =). Nevertheless, "older" revisions are MUCH easier to repair.you sure know your stuff! Mine are the older version then. If you would be located a bit closer I would be sending my N9 out right away.
