Jupiter Copper Foil Paper and Wax Capacitors

(1/4) > >>

steve:
I have been testing the Jupiter copper foil paper and wax 100 volt capacitors and not bad. Somewhat accurate in absolute terms.

Cheers

I agree, they are pretty darn good. I used Amp Ohm paper and oil caps whenever I wanted a sweet and transparent sound on my phono preamp, but they went out of business about 10 years ago and you can;t get them anymore. They were very highly regarded at the time. I then put in the Jupiters and ... when switching between them and the Amp Ohms - there is very little difference. Both great caps.

S Clark:
Has anyone compared the Miflex Cu in oil to the Jupiters.  I"ve been thinking about trying some in a crossover.  They're about 1/2 the price of Jupiters.

I am with you Scott. I like the higher temperature rating for stability and long life. But I also wonder how they sound compared to Jupiter and Duelands. Is they are as accurate as the Jupiter capacitors at less price, that would be fantastic.
 
Caveat: I have not tested a 600 volt Jupiter copper foil paper and wax capacitor.

cheers

   Steve I have a pair of 1.0 600V Duelund CAST copper caps sitting here doing squat right now. Switched to hybrid copper silver version foe awhile. Would you like to experiment with them ?
