hehe
even if I can't say that I understand purpose of every part in it ....... but that's anyway usual ZM's state of mind

The first stage is a simple differential jfet signal splitter...
second stage is differential mosfet (IRF630) I know, I know, but I have a bunch of them on hand and they sound terrific.
Third stage is a differential LU1014D choke loaded follower with a modulated voltage regulator on top
It's so damned cool, I can't believe it!
If my circuit resembles one (or more) of your's, Nelson, I'm sorry. But, when you think about it, I did learn everything I know from you (and the guys in this forum).

Flattery gets you everywhere.
You're a good teacher. I got the modulated voltage regulator idea from Zen tutorial 3. The LU1014D came in part from Zen 7. The source follower is something I've always wanted to try.
I hadn't intended to use the LU1014D--the 3rd stage was originally all Mosfet. The problem was the extreme waste of energy. The LU1014D does a dandy job of solving that problem. It also sounds great with only 12 to 14 volts. If I can get the 2nd stage to run on less voltage, this amp would be a terrific addition to an automobile--many thanks to Eric Gonzales for that wonderful idea.
