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

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..

I do have it but is just an idea that I had a few years ago I never tested I was just doing more layout practice those years

Hello, do you have the pcb file of the hv23 amplifier? The amplifier has a protection circuit.

Good afternoon

Jim's Audio does not send kx2 PCB's to Ukraine... for me there is a large problem. I can not get kx2 PCB's in Ukraine. Large request to share the gerber file of PCB for kx2 or kx. I will be very thankful for a help. Andriy.

Uau, muito bom, e-mail enviado. dimensões PCB?

Bom dia Luuker! Gostaria de saber se você fabricou esse amplificador, se sim, poderia compartilhar os arquivos.

English please

Eu tenho, mas é apenas uma ideia que tive alguns anos atrás e nunca testei. Eu estava apenas praticando mais layout naqueles anos.

Volte para aquela placa, Hermano Juan! Tenho certeza de que muitos apreciarão esse projeto, eu em particular.

Good morning Luuker! I wonder if you manufactured this amplifier, if so, could you share the files.

Go back to that plaque, Hermano Juan! I'm sure many will appreciate this project, me in particular.
