You mean 'at least 3rd time around'. The Apple
][ PSU is marginal, or at
least mine was. The 5V line was rated (IIRC) at 2.5A. A mainboard,
language card, disk controller, and 1 drive (i.e. not a very full
machine) exceeded that on my meter. Perhaps I was just unlucky and had
parts that took more current than normal, but I had a lot of trouble with
the Apple ]['s PSU...
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
