Atari 520 ST fm Problem Power Board Blown.

[Spanner]

Went to put it last night and it didn't power on,looked at the fuse and its black,Tested it with abit of wire and switched it on it and it went bang,a big spark came out of the board and quick turned it off,I think its got water damage,so I need hopefully just need to change the board for a good working one,is there anywhere I can get one cheap,looked on eBay and they are too much..?

 

Or is there any other way of powering it like with a pc power supply or something..?

I got a new power supply from here along with a few other upgrades. Great service and quick shipping.

On the original PSU the blue line is +12V, the two red lines are +5V and the black lines are ground.

 

Good luck.
