mosfet amp protection diodes

[Nelson Pass]

I think that this amplifier still needs some work.

I suggest that you take the power resistors off the Drains
of Q8 and Q9 and put them on the Sources, where they will
do some good.

I also suggest that you think about regulating the voltage
feeding R9 and R10 so as to stabilize the bias better, and
I think you could consider a cap to ground after R15 so as
to better filter the - rail to the front end.

thank you for posting

further testing bench and real life will be done with zener diodes included in the circuit plus the 2 recomendation of yours

thank you very much sir i will post results of that pretty soon
