I have a bunch, but more importantly, I have one that was potted with easily removable silicon rubber... not the hard, dark epoxy stuff... Anyway, I could reverse engineer it and make a schematic/slash PCB... IF anyone likes these things???
Yamaha NE-80100 Discreet OPAMP wanted?

In my opinion there can't be enough opamp projects floating around.

Yes...and I have a pair of these with some pm-1000 input transformers and no ouput transformers and they sound great on.....anything!
Really vibey but still clean...
Anyone un-bury the schemo?

I don't know what Joe's sources are. He tends to know about stuff so I'm giving him the benefit,but we won't really know until we crack that little sucker open.

I used a similar topology on a discrete buffer I added to beef up a bifet opamp output for a hifi phono preamp I sold more than 25 years ago.
While similar I used a lot less parts, and none of the dreaded evil electrolytic capacitors.
IMO this was serious over design on my part, but i did it because I could. 8)

I'm still working on it... reversing the PCB, I'm not very good at schematic layout, it always looks like mess when I get done... If I make the PCB and schematic in PCB Express and upload the files can somebody clean it up/check my work?

ya, I'll take a look, Pictures of the PCB etc would be helpful too. Thanks for doing this!! You rock!
