Once having had a significant fraction of a 25MHz '386 system fried
by a failed power supply, I strongly second the advice.  Even if you
manage to repair the supply, it may not be so kind the next time it
fails (i.e. one strike and it's out)!

Also, saving money in replacement power supplies might be false economy.
