Works well with most output types, but the EFIIIs work best, can use driven mosfets, 3 stage quasi, cfp driven darlingtons, cfp driven compound darlingtons that must be matched etc, the simpler the better
Its a whole recipe that makes it a worthwhile amp. There's even an old recipe adapted from tube amplifiers

Thanks Collins and TNT would you like to become familiar with it and tell us about your experiences with it? Lets do it 😉
I have opened up schematics, BOM and Gerber's for 48 hour for non commercial purposes. The tasting of a pie is in the eating, maybe you learn something may you don't, lets have fun. Size 131.83mm * 88.39mm 2oz copper recommended. Check post 1.
Thanks Colin, there plenty fish in the sea that's the beauty of choice. Where's the design your canvassing for or interests your representing? How does it compare? We can do a head to head😉
As far as I know, @ColinA123 doesn't canvass any vapourware.
With all the BS going around, it's only fair that we ask 'where's the beef'.
As he said, put up or shut up'.
But we all know this design is a figment of your imagination, right? In the literal sense.

Cross conduction , symmetrical current mirrored circuit can be "touchy".
Why not go for 300V/uS .... (below). 2 led's cancel the thermal for the VAS. made many amps with this.
Current sourced VAS cascode is too complicated ...
