Up for sale here is this set of 2 NOS vintage Cornell Dubilier Black Cat capacitors. They are marked .033 uf 1000v, and test right around .035-.037 uf, with minimal leakage/ESR. These will work fine at full voltage. These are nice ones! Please see my pictures for details, dimensions, and sample test results.
US shipping and handling is $5, and international is $18, no matter what quantity you buy. All my small parts are set up for combined shipping, so just use the "add to cart" feature and then check out all at once, and it will combine shipping. If you have any questions, please ask.
I have more capacitors and other vintage electronics listed--feel free to take a look!
