as others have said, a 100 Volt rated NON polarised electrolytic would be fine, there is a small benefit from using a polyester film or polypropylene capacitor, and at the small value of 1.5uF either could be had very cheaply. If you dont wish to take the other speaker apart, then an non polarised electrolytic will probably be the best option. Realistically, you could replace Both with a PE or PP film very cheaply. CPC, farnell, RS, Maplin will stock either. Paying a bit more at a local maplin or RS outlet might be worth it-no shipping fee for what would be a jiffy bag parcel of 1 or 2 pieces. Maybe 3 or 4 quid, max cost.

There is a way of saving a few pence.

Just buy two 3.3uF normal caps and connect them back to back (ie the two positives together) then connect the two outer leads (negatives) to the terminals. (Or the other way it makes no difference as long as they are back to back)

You can buy 3.3uF 100V caps from anywhere, Maplin used to do them.

Don't worry about the tolerance. Electrolytics have appaulling tolerances anyway. +100 -50% is quite normal.


Personally I would look for Polypropylene (MKP) or Polystyrene (MKS) just to suit the space that is being vacated by the electro's that are being replaced. Bear in mind the MKPs and MKSs don't have very long leads (8mm ish).

Is there much chance the actual tweeters are damaged?
You can test the drivers individually.

JUST MAKE SURE YOU PROTECT each driver from frequencies that it is not intended to voice.

If you use the original crossover, just remove the other drivers by disconnecting them. Use only low volume, it won't sound nice but you can listen to see if you get a crackle.

Replacing Sony Main-Stream drivers - Good Luck....

CPC are the main SONY parts suppliers but I don't know if they will keep speaker drivers.

CPC stock alot of Visaton speakers and a few MCM that are unbranded on their site. Sony I dont think they stock, unless theyre also unbranded.

Okay guys cheers for the help I can take them apart fairly easily tbh lol it was about 6 screws to get down into them. As for the capacitor I will probably go for a Polypropylene.

Would this be a good option then?
Solen 1.50uF 630V DC FastCap Polypropylene Audio Capacitor from Falcon Acoustics, the leading supplier of diy hifi components.

How could I extend the wires on the end of them to reach where they do currently? If I get them I am going to go for the 2% tolerance ones as well I think

I've always had pretty good luck with Solen caps, those should work fine. As for the wires, you should be able to nip them right near where they go into the existing cap and solder them onto the new one.

Ok nice one, cheers guys. I just realised that the postage on them caps is 4.25 which is pretty ridiculous :O think I might just see if I can find them somewhere cheaper. Maybe even see if I can buy some through work.

lol i did point that out jtaylor... For such items, small weight then its better to avoid falcon and wilmslow. There MUST be a local RS or Maplin near you, and im confident that the total cost will be ALOT less than your postage charge! FWIW maplin 650V PP caps, the yellow wound ones, are more than adequate. But what do i know?
