Well all this capacitor talk has me actually looking for the 5 uf cap.
When I picked up the 5065a it didn't work. This was in the late 90s and no
manual was available at that time.
I reverse engineered the system and guess what cap was bad? The integrator.
So not being all that smart, I hooked 2 X 10 UF caps in series. Been
working like a champ for 18 years.
Not obvious of what the downside of this approach was at all.
But I went out to mouser and have to say the selection of large capacitors
really is thin for PPS and PS. I did see the one picture of a yellow cap I
think from Germany.
The question really is what is the source and part number for a good cap.
does appear that the wima caps are carried by Mouser but may have long lead
