At first sight, some confusion with the power rating:
(a)The filename says '350W'
(b)The title below schematic says '300W'
(c)Looking at the supply rails (+/-50V), I wouldn't expect more than 200W into 4 ohms.

Looking at the bias diodes, I wouldn't suggest it as a hifi. May be good for sub only, in which case I think I would rather consider the simpler topology at:


I'll still study the circuit and see if I get some more ideas.
