Yeah, come to think of it, I do seem to recall
swapping a number of A2
PSU's back then. That was before I was willing to try component repairs,
so it was simple swaps of bad for good.
Well, if you're swapping in an identical unit, you'll not cure the
problem. The replacement is just as marginal...
That's _another_ reason why module-swapping is a bad idea. It assumes the
machine was correctly designed in the first place. Alas this is not
always the case
