I think it's safe to say that you are not the target customer for this amplifier.

Guilty as charged.

That said, if the X25 power rails were in the +/- 5v to +/- 10v realm with unlimited peak power and vanishingly low output resistance, I would be tempted. That is what I am working on in the F4 Beast thread.

Not for me....

I do still not understand what the two 100uF and 10k and so on and the new 8leg critter are doing.

:--))

But it is always nice to have exciting riddles to solve .....!

Papa puts his pants on just like everyone else: one leg at a time. Except, when he puts his pants on, he makes amplifiers!

If you mean the 8 leg critters on the output board, I think those are the TL431. They come in an 8 PDIP and a 3 leg TO92.
