hello all. last week my 30amp rivergate ps just stop working on me after 3 years of great service. i was wondering if anyone might have or know where i can locate a schematic for this thing. it is an older style( large cooling fins case, no fan, so it is not the bull dog line) this ps has got to be manufatured in the 90's but i got it brand new in the sealed case in 2005..my local electronics teacher is gonna use this ps in his electronics class for a demonstration if him and i can locate a schematic

let me know please

I spent many hours trying to find the same thing after my friend's quit working. There is no schematic to be had. The company went though massive changes many years ago and all the older ps were discontinued and schematics were "lost". I replaced every component on the board except for the crystal which I could not find a value on or anything that compared to it. My guess is thats had to be what failed since every thing was replaced besides that. Good luck.

The outcome is exactly what the other guy said.
I had a Bridge rectifier go in my old PC-30. I found one on-line and fixed it myself. It cost like $5 shipped for 2 of them. Make sure you get the right value though.
