Time flies. End of another year.
When I posted these a few years ago I stopped using them and because these have not been powered up in those years, I wouldn't be comfortable just plugging them in for a demo.
For that reason I'm now selling them AS-IS at a HUGE discount.
The task of going through them and powering them up carefully belongs to someone who knows what he's doing.
Your friend who fixes All American 5 radios on his kitchen table won't be up for it
I can tell you the last time I used them they sounded as glorious as they did decades ago
Think about it. Maybe these are for you.

NYAL Futterman OTL-1
built in 1984, I have owned them since new.
Special version - Only two pairs like this were ever built.
Built this way at the factory - NOT aftermarket
These are NOT prototypes.
XLR input connectors - the input is still single-ended (NOT balanced). two of the three pins are used
outputs have terminal block output connections in addition to 5 way binding posts
silver front panel
input level pots - which have been disconnected as they were found to be unnecessary
Corcom power line filtering

A few years ago I replaced the umbilical cords between the audio chassis and power supplies with much nicer wire than the stock "SJ" style original. The amplifier side connections are both crimped and soldered

I NEVER tube rolled in these (There wasn't any reason to as they were the best sounding amps I ever heard out of the box.) Sockets and plate caps are in excellent condition. The output tubes were tested and while back and are in excellent condition.
Feel free to ask any questions
