Beware of old electrolytic capacitors.
As a minimum measure the ESR and reform then.
If possible replace them.
This also goes for the oil/paper/foil type.
I had the mains filter caps in my 8/e (1972 vintage) go.
They were in sealed cans and I managed to sweat the solder out, open them up
and replace internally with modern mains filter rated capacitors and
re-solder the cans.

Subject: Looking for a vintage S100 power supply
Hey everyone, I am looking for a original S100 power supply
(transformer, diode and caps) unregulated and 8v/18v/-18v. Looking for
something fairly compact (like the one in an Altair 8800). If you have
one assembled, or ever piece parts, I would be interested in purchasing
it or trading for it.
