Nice design! Great work!
I miss the analog input and pwm oscillator, where are they?
Thank you microsim and congratulation for the design.

Indeed, if someone will make this project completed, and to be release to the DIY, then I can show the rest of the circuit

Regards

let me know if you can do that

Ok, i can begin to develop a first PCB of the digital stage.
This design can deliver 800W RMS with +/-80Vdc supply, isn't it?

Pleas take a look at the attached schematic, witch is PART of the full circuit.

There is still the limiter and the protection section.

I am only looking for some one, or two guys who can make this amplifier available for all DIY, then we make a group buy and so on, without cheating.

Since last time i have been cheated from some one.


Please I need good people


Regards

Hi MicrosiM,

I was interested in this design sometime ago but I didn't had much time then. you offered the schematic but I replied maybe later :) I can help if you want. Pls let me know what you would need me to do.

It will be a good idea if we discuss first, how we will separate the modules

I mean, Pre amp , Power module

Power supply board

Then we see who will make each part?

Good Idea!
But
What project do we have to develop? The first one(600W 80+/- vdc IRF740 based) or the other one(irs2092 ic based)?

the design is based on the IR chip with mosfets

let me know your ideas, also its claimed 800W

I like the topography of the first schematic (800W IRF740), also we could plan a little increase of the supply voltage(+/-100Vdc can deliver 1200W through 4ohm load). What do you think?
