Hi, I am working on the crossover inside a Kef Q60. The top end vanished from the speaker but I think I have traced the problem to two faulty capacitors on the cicuit board at the back of the speaker. One of the bad caps has the markings KEF 50V 36uF 58.36UOKABY. The other is marked KEF 1500uF 25V 58.1M50UKABY. Please tell me where to get replacements for these components. I would like to get as close as possible to the originals as I suspect a repair shop will just bang in any old thing. The speakers are sixteen years old and I read that electrolytic capacitors dry out in time. I also read that a replacement should be a mylar or polypropelene type. Any comments? Thanks for your help, regards gunslinger

KEF capacitors are "badge engineered" Alcaps made to very tight tolerances.

To get modern 1% equivalent electrolytics, I suggest you contact Malcolm Jones at www.falcon-acoustics.co.uk he should be able to sort you out regarding the 36uF component, I've no idea about the 1500uF animal though.

Thanks mate. I suspect I will end up having to solder two or three capacitors in parallel to make up the odd number of micro farads. It's a pity Kef don't just sell us the replacements on their web site. Their marketing manager deserves a good slap, so many customers, so many credit cards waiting, so little tech support.
