Hi Bob,
I long ago gave up trying to find replacement electro caps that are both electrically and physically compatible. Modern ones tend to be quite a bit smaller, so I just either make an adapter board to accommodate the different sizes, or stuff the new ones into the old cans.
If you have no luck finding compatible caps, those might be options to consider.
Cheers
Tom

?Am looking for replacements for the 2 large +/-160V filter capacitors used in the primary side of the SMPS in the 8662A synthesizer.
The original units are Sprague "compulytic" capacitors, rated 600 uf/250V.? Sprague p/n 32DR6593 They are 1.75" diameter, 3.125" long, with a screw spacing of .750".? The HP p/n is 0180-2835
I cannot find any supplier who has these units available, and the closest replacement units I can find are also non-stock, and are 2" diameter with a different terminal spacing.
Does anyone here have a parts mule 8662A they would be willing to rob the caps out of?
