Hi.
I've seen numerous power amps with an op-amp for input.
Looking in my old "applications of operational amplifiers" from BB i found two circuits and combined them into the ugly thing seen below.
Bias i class B. Purpose is only sub-duty below 200Hz and I would like to minimize current and have it totally thermally stable.
I know there are 10.000 good proven amplifier out there, and I'll probably never build this, but simulated it for fun in a 15minute break at work.
transistors are NOT chosen for ample voltage/current rating, - it's just what I could find in the LTSpice.
It is extremely simple. Probably too simple. BUT, would actually work?

An externally hosted image should be here but it was not working when we last tested it.
