I'm on to building the HV PSU for the 8877.
I have 2 alternatives for filtering - a used but good 54uF 4.2kV oil-filled
Maxwell or a string of 10 new 470uF 450V electrolytics (with 45K 10W
equalisers). They work out to roughly the same cost.
I'm tending towards the oil-filled cap because it simplifies construction.
Any comments on either? I've seen comments here regarding equalising
electro strings and also read things about forming them. Do oil-filled caps
go off over time? Is it OK to mount them on their side?
