I recently picked up a Suncor SS 137 sweep circuit analyzer. I want to recap it so that it works reliably before I start using it. Most of the capacitors inside are normal values except for this one. It's 25MFD @1,000 volts. I can't seem to find one anywhere what do you guys recommend?
If u look at a schematic I bet it's a .25 mfd.

I'll take a look again in the morning. I was thinking of clipping it and trying to measure it. Unfortunately my capacitor tracker doesn't go to a thousand volts so I can't check leakage.

Doug you're right I tested it with my meter and checked the schematic its a . 25
Yup. A 25mfd @1 KV would be a pretty big & expensive
SO these days you may not find a .25 mfd but can sub
it to a .22, .27 etc at 1500 V probably. It looks like
its just a coupling cap to a drive out so something close is fine.

It looks like a film capacitor. I would be tempted to leave it alone if it is leak free at the highest voltage on your capacitor bridge.
