I'm nearly positive that pin 5 should be -12v and not -5v. It makes much
more sense for it to be that way (consider that RS232 is +/- 12v).

That, and what I remeber being the difference between the C=128 power
supply and that for the A500 being---other than the power switch---that
the C=128 supply provides +/- 9v where the A500 supply provides +/- 12v.

I can double check this in the owner's manual if somebody doesn't provide
a definite answer before I get home this evening.

Heat failure due to poor thermal protection and overloading.
