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!

You might try ebay at this number. It is 100 volts but going up in voltage
should be ok. There are others if you don't mind higher voltage.

Yes,
That is the axial I found.
They sell it on their website for $0.50 with $6.95 shipping.

Thanks, Mikek

$1.45 in singles for a Panasonic 2.7uF 100V film cap from Digikey.
ECQ-E1275KF Radial lead (but not a can).

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.

Maybe very careful surgery of the old cap, stuff the
new one inside the hollowed out old one to get the
old "look"?

It actually split the plastic cover and doesn't look to good anymore.

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.

Polarity will not be a problem.

The Rubycon 35V rated caps must be pretty good :-)

They *are* pretty good aren't they? That surprised me a bit, putting a
decent brand name inside a fake.

Hmm... perhaps the Rubycons are fake too... Is there something else
inside them too?

The Rubycon looks like it was salvaged from a discarded board.

That's what they want you to think.

*ding*

Look more closely at the logo. It's "Rulycon", a fake designed to look
like Rubycon.

These came out about the same time as the "bad caps" scandal a few years
ago.
