Repair shop in New York

I can second the Soundsmith suggestion. They do fantastic work.

Also, Hudson Valley Hifi in Cornwall NY. 

Yes both are out of city limits, but they do it right.

Still interested to find a repair shop in the New York area

I’m just learning that if I use the pre out for the sub, the pre and main have to be coupled. I had it wrong. 

Everything seems to work again now - not sure what the issue was,

Random. I wired everything the same.

I’m suspicious that there’s a weak contact or something inside that’s acting up every so often. I may still getting it checked at some point. 
the weird thing though is the pre out/main in: It acts as if it were reversed. I have the sub wired to the pre out. When the coupler is in the off position (pushed in), I get almost no sound on the wired mains, so have to crank the volume up high to hear something (normally that would be deafeningly loud) but I can hear the sub. When I have the coupler in the on position I get sound split/distributed to the mains and the sub - almost normal, maybe ever so slightly muffled/distorted. 
What does tha mean? I’m a bit scared as that seems to be the reverse of what I should do. If I use the pre-out for the sub, pre and main should not be coupled, right?

Uh, that’s far! But thank you, Rich.
Maybe a day trip on a weekend sometime in the future. 
Meanwhile my backup, a Nikko 1219, will be on duty.

if anyone knows of a closer option, I’d appreciate it.

My dad fixed TVs and stereos for a living, so I know how difficult it is to get a good technician to fix equipment.

Years back, I had two Marantz receivers (2216B and 2240) repaired by the Soundsmith in Peekskill.   Excellent work, but costly.

I hand carried the receivers up to them.  Didn't trust shipping.  They are about a 1/2 mile from the Peekskill train station.

There's definitely a serious issue with the R-2000.

After cleaning, deOxit, re-wiring speakers, using different speaker channels, different sources, even radio... no sound whatsoever. It's dead. Why?!

If you know of anyone in the New York area who could fix it, please share.
Thank you!

Thanks, Rich from Queens.
