I cant believe I'm the only one experiencing this.  It takes a few
months for the discoloration to appear, but every single MC I buy has
done this (or maybe I'm the only one who cares :-).

My AC is 110V, kind of on the low side from others I know. Normally
120V is common.

It looks like a 1/2W zener to me. My plan was to go find the same
voltage (I now know its 18V) in a 1W zener. I think I'll also try your
suggestions and try to put a heat sink on it, maybe a piece of
un-etched FR4 PC board. It'll take several months to know if it works
though.
