This thread may be useful if you are looking for a replacement PSU.

I know I might be stating the obvious, but sometimes the smallest and easiest things are overlooked.  Have you checked the fuse in the plug ?

To cause damage while turned off, the power would have to spike high enough to arc across the open switch contacts.
It's not impossible, but I suspect that you'd see damage in devices that were powered up on the same circuit long before that would happen.

Its a  bit late,but i recommend you put your equipment on a UPS(uninterruptible power supply). Even the cheapest ones can usually prevent things like this from happening.

You could check the power supply with a multimeter to get a idea if its working. Changing it out with a known good one is easier of course.

I guess checking it with a multimeter or a replacement PSU being easier depends on which of those you have available, but I am guessing more people have a multimeter, than a spare CD32 PSU.

Mechy used to convert and sell some great PSU's for the A500/A600/A1200 and CD32.  I am still using one of them myself for my A600 and would highly recommend one of them, if he was still making them.

Mere static electricity can easily reach a high enough voltage to arc 1 cm, so I'm sure a lightening strike covering a much higher distance has the ability to jump the power switch (plus I lost a high end Sony amplifier this way that was turned off during a strike in the yard).

I think he was talking about curcuitry and devices that were powered on when lightning strikes the power line. They would have been damaged heaviliy.

 So it may are may not be a co-incident that his gear failed that time.
