Has anyone ever built this amp.
It was found at the url below. There is also a pcb and overlay diagram there.
Try this one, and click on 350W BD750A BD751A
Regards, Pierre Lacombe.
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.
