Element 14 Audio Grade Capacitors

Rocketeer

Hi All.

Hoping someone can advise.

I inherited some early vintage Japanese Loudspeakers needing rejuvenation.

Nothing fancy, just loudspeakers from small systems.

I think their worthwhile as they're from a bygone era.

They're fitted with various electrolytic capacitors maybe 40 - 50 years old.

Mostly single caps servicing the tweeters & ranging from 1.8µF to 3.3µF.

I don't want to over capitalize so thought electrolytic over film as they are not cutting edge hifi speakers.

Is there anything recommended from the element14 catalogue to replace the existing caps?

I'm open to both electrolytic & film depending on performance vs cost vs suitability to each application.

I haven't removed any of the caps for a test, but am going by their age & the general life of electrolytics.

cheers

    i don't no how many speakers i would have fixed over the years,Most of them would have the rubber surround collapsed because of age,

    i would have needed to repair more broken legs of components on cross over boards than replace just replacing caps.

    i am not an audio file but i will say the heaver solid cabinets (even home made) do have better reproduction 

    over your average Japanese box

    then paper tweeters not as good as some others.

    in Australia i would look at WES components for drivers

    can you use an ESR meter to check caps first.

    can you run a frequency sweep one cabinet original and other after changing caps.good luck.

    Thanks 90.

    I have a meter which performs resistance, capacitance & inductance measurements.

    I have about 8 pairs of speakers needing attention. but limited time.

    At this stage I'm exploring possible sources for audio quality electrolytic caps as well as reasonable but economic poly caps.

    Once I can source parts I'll get into removing bits to test.

    I don't want to do this prior to establishing a parts source for fear of having many speakers in various stages if disassembly.

    Also, another key part of my exploration is to get an engineers point of view regarding caps & audio.

    Today I repaired a 70's vintage Amp which a friend brought to me for help.

    Surprisingly I got it going and then started testing some of the speakers I've accumulated.

    Some of these speakers have potential and I'm looking forward to playing with their crossovers.

    I'll replace caps in one of a pair and then listen to the difference on mono.

    Just hope I can secure worthy well priced caps.

    I'm learning that caps have varying functions.

    In some applications noise is not an issue, whilst audio demands low noise as well as other attributes.
