I think he's a bit optimistic claiming 200W per MOSFET.

True, I really only need 150 watts or so, if the design was decent it would be a good deal.

The power loss isn't 200 W per mosfet. 400 W 4 Ohms doesn't seem impossible if we talk home use.

NO way that can put out 400w with +- 45vdc.

Looks like a Elliot sound 101 clone, but not as refined. Stay away.

An adaptation of the Nelson Pass re-do of the Citation 12, about 50W or so into 8/R with the stated B±.

For anyone thinking about trying this design beware. Two of the diodes shown on the protection circuit are in backwards according to the schematic. Who knows whether or not this is intentional. There may be more gotcha's on the amplifier.
