MOSFET Amplifier IRFP240/IRFP9240

[smartx21]

HV25 is for P.A. use. Choose a more refined circuit for home use. I suggest SARA.

I've enough good sounding amps , I need power to juice the four 12'' woofers .
I already have the Thel Audio Accusound 100 bud I need a second one that can perform the same . See the pic of the Accusound

I quit.

You must like the sound of woofers bottoming out.

Btw, your idea of adding one extra output mosfet would not work. Because you lowered the supply voltage. See, original first post calls for +/_80 volts. You asked if you get more power with one extra output, but with +/_75 volts.

That's why i suggested to get behringer or lab gruppen. Perhaps classD would be for you. Perhaps start new thread, ask question. I used 2000 watts behringer for our company amateur music group. Used to be soundman, just for fun.

Don't like Class D . Build Purifi and Ncore non of both beats my Accusound regarding attack , bite ,grauwl and bass sound .
Against the Accusound both Class D amps sounds dull and flat .
My personal opinion off course .

How much power ( Watts ) would this version have with 75 Vdc rail voltage by 8 Ohm ?

(50^2)/8 = 312, depending on the weight of your ptx, could be lower..
