An externally hosted image should be here but it was not working when we last tested it.
I saw some other op-amp biased fetamp so I thought I would post this one. No bias circuitry is drawn in the picture. Just the basic amp. As it is now it runs in class C. Not any sweetsounding but its just an idea.
Any thoughts or comments????
Looks like Sumo Nine(+), except mosfet output, deseign by James Buongiorno.

Why should bias be tough?
Perhaps the following completes the picture:
This is a modifcation from a design in "Radio" August, 1984 issue, pages 35-37.
Don't ask about the sound, because I never got around building the first time I saw it and later I found Renardson's 7-transistor amplifier, which is technologically superior to DIY.
