Repair shop in New York

Thanks, Rich from Queens.

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!

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.

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?

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. 

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