ok I'm ready to build one of these....
I want to power a gainclone type amp with it.
I'll need , +/- 30v right? I will only need a 300 watt psu or so, as I am only gonna need 60 watts per channel ( x2 ) but I might want to add two more channels.
I can't decide on a design.. I have seen a few variations online. Is Rod Elliots good? ( I trust his projects a lot, just making sure though) will the toroid core he sugguests work ok for this wattage?
Also, how in the world can you make a pcb for something like this?
as I understand, the tracks need to be huge to carry the amount of current needed. Id be using radio shack copper pcbs and home etchant...if thats a good idea, if not ill send out to have some made.

Buffers
Hello Mr. Luka
The SG3525 is driving the Mosfet gates with NPN/PNP BC547/557. Is it the buffer you talk? It´s the same drivers in Sergio´s design in ESP what I use. About Protel format/viewer software, do you Know how I do to free download in the WEB?
Thank you very much
