Before it's put on a slow boat from China
I need a 2.7uf 63V non-polarized capacitor for a speaker crossover.
It is a radial lead 10mm x 22mm cap. Ebay has them from China. (slow boat) I've checked Digi-Key, Mouser, Allied, and Newark. I've also checked several speaker part sellers. I have found an axial lead cap, for $0.50 plus $6.95 shipping. But I'd prefer a radial lead. Have any other sources? Refoamed a set of Pioneer HPM 700 speakers, also put two OEM tweeters in them. I thought I was done, listening test showed no output from one tweeter, found bulging cap in crossover. Argh! Mike |

There are others if you don't mind higher voltage. 321699248915 |

Yes, I see I have other options, I was hoping to install a cap that looks like the original 1982, 10mm x 22mm capacitor. I may not get what I want. Thanks, Mikek |

Mike You can use two standard caps back-to-back (+ -- +). But they should be 6uF caps. Back to back, they will test out at 3uF. If you screen them carefully, you should be able to get very close to the 2.7 you need. Or, use 2.5uF caps as electrolytics tend to run 'fat' rather than 'lean'. Or, use a film cap, full stop. http://www.mouser.com/ProductDetail/...B&kpid=3343101 Polarity will not be a problem. Peter Wieck Melrose Park, PA |
