Hi! Mile

please confirm me again whether it will work for pa applications??
or i will get oscillations like b500?

so that i can buy parts and start building.
i need an amplifier which is more durable.

I suggest you HV23 MOSFET Amplifier IRFP240/IRFP9240

Drawing layout is just something easy,many people can do that, but design a very good schematic is something difficult,need many years of experience and complex math like what You've done.

Hi comasus,
That IRF240/9240 is not too expensive, I bought it here cheaper than SanKen bjt transistor

I suggest this amp with BJTs, and you don't have any stability problems
QUASI Amplifier for Beginners

I have already tried this amplifier but not satisfied with that sound you can see my comments in that thread

Hi Sir Mile, apologize in advance this might be a silly question and beyond the discussion, can I use this schematic for power supply with an output capacity of 48 Volt 10 Ampere? whether there are components that should be changed or added? please help me. I needed.
Thanks. regards Damanhuri.
