Guest Posted September 24, 2002 Report Share Posted September 24, 2002 I am refurbishing a pair of KLH 17 speakers and want to replace the crossover components. I have identified some resistors and a capacitor with a value of 8UF 50VNP, but what is the other capacitorlooking component. It is the size of the 8UF but has the followinginformation " TEMPLE, 0015-00-0122, RED2X2 UF 50 VNP, BLACK COMMON,65C 7212". Does anyone know what this is? your help would be appreciated.

JULIANKOWA I'm sure what the vaue is either based on your info. I suggest you remove it and take it to an electrician who has capacitance meter and get it measured and then you'll know.Carl, The SpeakerDoctor Link to comment Share on other sites More sharing options...

This is done in the KLH5.Bob Link to comment Share on other sites More sharing options...
Guest Posted December 19, 2002 Report Share Posted December 19, 2002 Thanks for the post.I am restore a KLH 17, I hooked it up to the amplifier, one tweeter had no sound, the other tweeter had real weak, low volume, I pulled out both tweeters, took it to the shop, hooked them up with a audio signal generator, and sweep the audio freq. through it, and both tweeter worked.I haven't digged into the crossover yet, both woofers work fine, so do you have any idea what the problem may be? Could the crossover components go bad? Bad wires? I've seen bad wire from aging on a old Dual turntable, also, do you have the schematic and component values for the KLH 17?Thanks for your help.PS, I have a pair of Genesis 20 in mint condition, the only thing I've done to it is refoaming the woofers (normal for 20 year old speaker), it will be my next project for upgrade.

Could be a capacitor. I recently acquired a pair of KLH Fives with no tweeter output from either speaker. It turned out to be the same dual-section non-polar electrolytic cap in each box.Bob Link to comment Share on other sites More sharing options...
Guest Posted December 20, 2002 Report Share Posted December 20, 2002 Thanks for the info, I'll check it out.Are the components in your speakers connected to the crossover by wire nuts? I am curious if that's was how they did it back then.Also, how would you take the old wood veneer off? I like to put new ones on. Link to comment Share on other sites More sharing options...
