So I built a few amps a few years back. I had a great deal of fun but found myself with less and less time to mess around with things. I recently discovered a board that I had bought and never finished. I spent all day trying to figure out what it is online and failed. If anyone recognizes what it is please let me know. Thanks!!!

Correct, a JC-2 copy. Plenty of these around.
I see they only charge $6.60 USD to assemble and test over the bare kit price.

Thanks! It was driving me crazy! Yeah, if I remember an assembled board wasn't much more, but I like to solder.
Does anyone know which fets i should use? It didn't come with any. In fact most of what it did come with was wrong, as far as resistors, etc.
On the PCB there are signatures BD139 / 140 🙂 This BJT.
