220V/50Hz to +/- 55 volts about 800 watts

Hi!
I need lots of help in making a switching power supply from 220V/50Hz to +/-
55 Volts about 800 watt (for 2*300 audio amplifier).
Could u help me? (for example a schematic and/or pcb..😎 😎 😀 )

Do you really expect somebody else to do your job for free?

That's a fairly large supply. After the electronics, magnetic and thermal design are very serious... those won't show up on a schematic either... SMPS's this large are not really right for a simple schematic copycat.

Sorry - 🙁

Eva: not really for fre🙂
If somebody would it do, then I will pay him something😎
Here, in Hungary, sme people would do it for 15000HUF, about 60-70 Euros, (~ $75-80).
I know taht it!s not simple schematic copying, but I think it would help for lots, who wanna make power supply for his/het power amp...

"Here, in Hungary, sme people would do it for 15000HUF, about 60-70 Euros, (~ $75-80)."
sry, the full power supply costs that price that I wrote (ot only the schematic🙂 )
