I am considering using two modern +5v at 25A switching power supplies to
replace  the +5V source ( leaving the original -5V at 2A,+15 at 2A,-15 at 2A,and
+20 at 4A as original) in a PDP-8A.
My intent is to increase the reliability of the system. I have had trouble
with keeping the G8018's operating. I occasionally trip the breakers on
startup. I am thinking bad filter Caps. Perhaps someone could give some
opinions on this (Crazy) idea.
