And that is just the beginning!!

Well hahaha yes indeed.......Much nicer folk here in the Sansui forum too, its a clicky world over there in the Mc forum......
Ahem. Don't make me have Gibson ban you from the Mc forum!!
Carry on ...
That would be a loss not to have ya' brother!Well, best you go and tell on me then.....Because you know, I'm pretty much done over there....

Everything is holding well, stable, so I put the front on and the bottom on, I'll run it for a few days and then recheck everything.
Its on the test bench now running the turntable.....really nice clean and detailed sounding Phono pre, pity I don't have a MC cart to try out, but none the less, the VMS20 is great, we are getting a nice fat sound!!
I'm also waiting for the lamps to turn up, so this is as far as assembly goes right now, they should be here courtesy of Dave the resident lamp guy next week.
Really all in all, apart from a couple of "I know better than you" and "gottcha" moments and wild goose chases with a couple of rather odd issues, this amp has seen little work, I think its very low miles....
But I suspect there were a few issues that came up which had it destined for storage and then forgotten about....
I also think its a late model, lots of grounding amendments by the looks...
It is a JDM model so 100V, I will have to see what the owner wants to do, plenty of 2:1 transformers around that give us 115V down here in NZ, but really, that is too high, I'm running it through my Variac into a 115V step down, I have it set to 100V exactly.....nothing gets warm, even when I had it really cranking for about a half an hour...
Really impressive, but I would say it would be a different story running it all the time on 115V 15% overvoltage...
Few pics....

Nice work there. Mine runs almost every day and it beats all other stuff I have. But I still have to compare it to my Yamaha B1 when that finally returns. Just like Hyperion I have to find time to finish it completely. I still have to put the restored phono boards in, but that means I have to unplug it .
However it should get warm especially the phono boards which run in Class A. Did you already test the stability of the amp?
What would be a good replacement for those green reed relays?I noticed a Hitachi epoxy covered reed relay back several posts. I presume it's a headphone relay in this unit.
IME, they are proving to be unreliable little buggers as time marches on. The green epoxy coating stuff eats into the copper windings around the two encased glass reeds. Much mid to late 80s Japanese gear had them inside. Just a heads up.

Check US Relay manufacturer Struthers-Dunn: RR2A-24VDC, MRR, RR Series - Axial Lead, Shielded Reed Relays...I have never seen replacement relays with the same package as the original green ones, but that doesn't mean they don't exist. (NB: also used in the AU-919 and probably others).
yeah same as what McIntosh use for all their input/output switching....in the newer modelsWow - good find - providing "Universal Electronic Supply Co" (based in the US) will allow you to buy in singles (one's and two's) - they would work nicely I think. (Rhodium plated contacts )
