This has
happened to me on several MicroVAX II PSUs and it is the mains
filter capacitor. I have replaced them with these:

(N70CN for the one that failed)
I recommend changing the other one at the same time as it won't be long
before that one goes too.
I have at least 4 MicroVAX IIs. Should I order spares...
Never hurts to have spares. I have spare 6502s and 6809s for my machines
in case those fail, too; you can never be sure when you'll be hard up for
one.
