Default John Curl amp

I would like to build an amp by John Curl. The only one I see is on the class-a amplifier site. I could do the board layout only if it is ok with John.

www.marklev.com has schematics for the JC-3 and the ML-2. As I understand it, the JC-3 was the prototype and the ML-2 the (greatly fiddled-with) production version. I don't remember offhand who did the fiddling--Tom Colangelo, perhaps? It's been a while since I used those particular brain cells. In any event, the ML-2 is clearly a more complicated circuit than the JC-3, although if you squint your eyes just right you can see a resemblance.
I'm not aware of any other schematics by John being available, unless you want to count the JC-2, but that's a preamp.

It's OK with me. Once I publish, I expect it to be copied. However, upgrade all the active parts.

I have thousands of caps, it is just 'good' caps that I am short of. What kind of caps were you referring to?

Interesting Mike,

Would you be interested in the ML or the JC variant?
