Evening all.Just thought I share this. I have build a quasi output circuitfrom DIY AUDIO. It is using an IRFP 250 mosfet in conjunction with a MJL3281 transistor on the output stage. I have build it because the wise people say it sounds sweet with majority H2 harmonics. Well it does sound good and sweet as they say. ;D Running from +- 42Vdc rails you get about 70Watt. Still have to load test it to see if there is no smoke ! Used a clamping bar to secure the outputs.
