Hi Stee,

maybe it's just me, but I don't understand your drawing. If that's the full amp on the right hand side, then I would say you really don't want to cut the input signal with diodes. Sure they're necessary for biasing, but in that case you would need to AC-couple.

For AC-coupling a set of resistors would do the job as well. Or a current source to boost PSRR.

But maybe the whole mystery lies in the left hand side of your drawing?

Have fun, Hannes

I need to pay more attention, sorry!

I strongly suggest to read this topic...
What to read on SS amp design?

Learn before, build after!

Default Class A biasing

see the point of work for final bipolar
need 3R6 ohm on base to have 0.9V with 250mA from Mosfet

Talking on being creative, no one has stick his finger in the 220VAC outlet, on purpose. You could be the first one!
