i am beginning to lose my patience and almost 10 pcs of different sizes was used but cant find the bastard problem.

I can't seem to open any of them. I thinking about doing something like what you have built but using the LM3886 chips, all though I'm not sure if this is a good idea

Where con you buy the core at?
You stated that you use an ETD core, from where, I did a google search and came up with like 10,000 hits. Any suggestion?

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.

Thats exactly what I did. Except Radio shack only has double sided board around here so I ordered some online. If I still had a functioning scanner I would upload my artwork. I used Rod's design and it works great.
Hello, I want to ask for the file smps.zip...
What is the maximum power of this SMPS with only one IRFZ44N on each rail, and how can I calculate the windings for the ferrite trafo (can I use R34-Kashke ?) for my voltages (ex. +/-35V) ?

Protel viewer
Dear Mr. Risto80
Congratulations!! Great page about TL494 and SMPS. I build some projects too. But, in this moment, I need the Protel viewer. How can I do to download it?
Thank you very much.

ESP SMPS
Hello Mr. Sergio
Very good your SMPS design with SG3525. I build it, but only with four IRFZ44N less regulation and old toroid of car amp. I want build eight mosfets. No problem with drivers??
Thank you very much.

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
