Help Identifying Cap.....

dmongrain · 30th May 2009, 07:05 PM

I need help identifying the values of this cap to replace it, I'm hoping that someone can help.......

This might not be a cap... The lettering leads me to think
it might be a MOV... Metal Oxide Varistor

Forgive my ignorance, but what does that do on a crossover? I did a little search and could only find articles relating to surge protection, is that what it would be used for?

lets see another photo, top real close and back side real close.

Is that a Pioneer speaker?

40 volt varistor to protect the tweeter imho

Or maybe one of those self-resetting fuses,to protect the tweeter?

To be honest the crossover is from a cheapo speaker that I am messing around with, I'm trying different things like bracing, stuffing, etc to see what effects they have on the sound.

I can take a pic of it later today (not at home right now...), but from memory the disc is about 3/16" dia and not very thick with no markings on the back.

From memory, there is one resistor, two caps (electrolytic I think...) with two inductors, again, I'll take a pic when I get home.

in your pics pay extra close attention to the legs of the device and how they go into the body, is there a bulge on the body or do they seem to just go inside?.

Just scrape away some of the coating to see. Might be my poor eyes
but I think I see a little bulge from the right side wire in the middle.
Also the left leg seems to do the same on the backside as far as
it can be guessed from this angle.
