I have an old HT-41 apart, it has the original filter caps. I brought it up slow and got the filter caps to level out and they appear OK. I took them (6) out individually and charged and discharged them on a regulated 450 v supply and I'm seeing between 1 and 4 ma leakage but it seems to be going down the more they are under power. They have 20K equalizing resistors across them.
The original caps are about 4" x 1" and rated 100 ufd / 450 v / 85 degree
The guy I'm working on it for gave me some new caps that are 1-3/8" x 3/4" 105 degree 100 ufd 450 v.
Any opinions on if the smaller caps can handle replacing the old ones or should we look for bigger cans?
Talk is cheap... except when Congress does it.
