Laterals on
Detail:
The FETs are now connected in place of the darlingtons. No oscillation with 100ohm gate resistor in the lower FET. No resistor in the CCS FET. Not tested with no resistor in lower FET.
Status:
Stable and playing music at the time of writing with gain of ~7.6 .
Sound Quality:
Later. I'll be listenning for some hours and upload the details, probably tomorrow evening. This is my first time listenning to a common source class-a amp.
The crossed hexfets are not part of the circuit. They just sit on the heatsink and are part of another amp temporarily disoconnected for testing this amp.

mmm... Where to go?! Common source? Common drain? Confused.
Listenning done and here's what I heard and felt.
Well, It's Zen; Two BJTs total in the circuit. Death of Zen? Dunno. All I can say is that it sounds remarkable!!! And ya, NO instablities. Unlike Zen its output is non-inverted, but Like Zen when it sounds, it just sounds, and mutes all other sounds. Well, It IS Zen. My style Zen amp, with a sprinkle of BJT. 🙂
As vids talk more than pics this time I show it through a video, where it's loaded with one of my favorite tracks.
