MOSFET Amplifier IRFP240/IRFP9240

With +/-33V single pair of output FETs is enough, you can see circuit in post #239, and wireing in post #145. Bias adjust to get about 20mV on 0R47/5W resistor. Power will be about 50W on 8R load with +/-33V DC. You can use this amp for any aplication, and I think beginer can build it with my help.

You have to take into consideration transients when deciding on a power supply.

On my first self design MOSFET amp I used +/-40VDC and was surprised how quickly the transients got clipped.
I now never use a supply less than +/-60VDC.
I do play quite loud so perhaps you dont need such a high voltage.

I suggest +/-75V. Amplifier with +/-33V can be realise with LM3886 or TDA7294.
