Re: Creative Gigaworks S750

Hello!

I'm fighting with some nasty S750. Firsty I assumed that standard procedure of cap replacement "will do", and actually it fixed up secondary PSU.
By rush, I've blown two of 470/250V caps on primary PSU, and then it became clear on schematic that IRF740 are blown (actually mostly Q1 is getting killed) and these two caps are getting rectified 230V.
I replaced the mosfets, but the unit blew them again. I was measuring around the board to see if something is strang, but with no succes. I have 2 more of these PSU...
