Hmm
I dont see the point of the opamp buffer.
The output stage looks funny.
Only 2 pair of MJW21193/4 at 75V?

May be need another pair of paralleled final devices
if you need to use at maximum POWER

I agree , this looks outright deadly.

I would not hook my other 1500VA to it , spray the room with molten copper and kill the kids...

It looks like an Elektor design. It's a more or less conventional amp with a power stage without feedback. Is that good?

Definitely, character of distortions on speaker's output will be different.

Juergen Knoop · 6th June 2009, 07:51 PM

me recognised the elektor odor too.
Anyway, is there any hint, that those circuit is genuine and not 'improved' by dear Stee?
