It's good that these caps are so readily available.
But on the other hand, I don't have any sort of power supply
at all, for either of my two PDP 8/S machines. Sob.
Being in a 240VAC mains country doesn't help, since I understand
the original DEC supplies were 110VAC input only.
But I'm not comp

Amazon is your friend:

BTW, Genteq is a reputable brand. It is the former GE capacitor division,
hence the name Gen(eral Electric)teq(technology).

I don't know your location, but the surplus electronics/electricals
vendors here in the US tend to have lots of the the older oil caps (no
PCBs).

Has anyone replaced the capacitor in a ferroresonant power supply with much
success? My current understanding is that the capacitor and transformer are
mated as a pair, so replacing just one of them would require careful
consideration.
The PDP-8/I I'm working on has a 704A in it, with a GE 8uF 660
