Hmmm... one of mine had a faulty rectifier too. Not
hard to diagnose
or replace, but I wonder if that's a common failure? Another one had a
bad filter cap -- but it had died of age (leaked) rather than causing a
short. Another common "problem" seems to be whistling from the coil,
if it's begun to delaminate. Probably a sign of previously running
hot, and not necessarily anything to worry about. Several of my
"brick" PSUs had faulty bulbs, and I found the easiest way to fix that
ws to replace the bulb with an LED and a resistor, as found on the
later versions.
I've seen a number of the rectifiers fail, so I would concur that it
is a common component to fail. Also, those supplies have always
whistled, even when new from the factory.
