Speaker Wiring Help

[mushav66]

I wasn't sure where to put this, so i figured I would give live sound a try.

I would also like to admit that while I have rudimentary skills soldering electronics and understand signal flow, I do not know much about electrical components and what they do.

I was given and old Sano speaker enclosure that houses a woofer and and two horns. When I got it, one piece had been broken off. It was soldered one end to the lead and the other to the ground of one of the horns. I cannot find the part in any stores and I was hoping someone would be able to tell me what I could use to replace it. It says:

BRNP 2-50
2 MFD
50 VNP

CORNELL
DUBILIER
7149

Any help would be greatly appreciated!
Thanks in advance.

That is a 2 microfarad nonpolarized electrolytic capacitor, 50 volt working voltage.

You should be able to find a replacement from speaker parts suppliers.

The important thing (aside from the correct capacitance value, 2 uF) is that it is nonpolarized.
Also, it should be rated at least 50 V; higher generally won't hurt, but don't go a lot higher.

Standard electrolytics are polarized and cannot be used in speaker applications. Speaker parts
suppliers commonly have these nonpolarized types, but any large electronic parts supplier should
have them also.

I'll take a quick look.

That capacitor basically forms a simple crossover to pass the higher frequencies
to the horns and block the lower frequencies from reaching them.

Also, in the good old days, mfd was used for microfarad.
Nowadays, it's uF. That 'u' represents the greek letter mu, for micro.

Thanks a lot. I really don't know much about this, so listing it all out should help greatly.

If you can't find nothing closer, this would probably work just fine:

Also, I added a couple notes to my first post, just for some extra information.

I was able to go to a repair shop this morning and he found what I needed, got it put in and put back together. Thanks for your help.
