I've found this schema
in an old rewiew. I publish it becasue it was my first good sounding amplifier.
Excuse me but I
still love it, with all it defects. I think it dates back to the
seventies.
I used IRF 522 MOS, with a Source resistor of 0,22ohm 5W to equalize the current in each device.
WARNING THE SCHEME
ARE BIG!!! SO PREPARE TO WAIT.
