Now we can see the Ju-Jutsu Amp (SE Stereo) in its true light and simplicity.
It is simply a pure two-stage amplifier, in real linear operation,
with a pristine DC supply, and no current in the OT.
I've stuck in some LEDs to bias the first stage, as some people might want to try it.
When the Mu-Follower is understood as it really is,
a sophisticated power-supply regulator circuit combined with an ideal load,
we can see plainly how the amp achieves near-perfect distortion-free operation.
The only two caps in the signal path are in the PS chassis.
