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?
