hi , i am looking for replacement capacitors for my beovox 3800 2 ohm speakers.
they are around 30 years old. i read in this*thread that replacing the caps might improve mid and upper range performance.
does anybody know a decent uk supplier (or overseas) that might sell this kind of thing? I had a look around a few sites but i couldnt find any that match the exact specs

Thank you very much!

Hi
Try Wimslow audio ( who specialise in speakers ) or Farnell ( who supply electronic parts )
I am not sure how familiar you are with electronics but you need a capacitor that is 25 volts or greater and 40 mf plus or minus 10/15 percent.
I would recommend changing all the capacitors if 10 years old.

i had a look at the wilmslow audio and the only 40 micro farad ones they had were 630 v
if i am only after 25 volt ones will these still work in there place? i dont want to compromise if i can.
If i were to add up the capacitance from two caps is that going to compromise on sound in any way?
thanks people , i really apreciate it. my speakers are good as it is but the upper frequencies could be better, hopefully this will help them out.
while i'm at it does anybody know of any decent amps capable of running 2 ohm speakers?

Krell and Krell Klones.conor4 said:any decent amps capable of running 2 ohm speakers?
see the KSA50 thread. PCBs still available.
I'm not sure everybody here is aware that these parts are probably polypropylene caps (MKP) and these do not need to be exchanged after 10 years. That's about the rule for electrolytic caps.
Well, but that's DIY, so go for it if you want.
Far higher voltage ratings are no problem, need just much larger space.
All the best, Hannes

I will guarantee that B&O have not used an MKP 40uF 25V in this speaker.i had a look inside and the one of the existing caps is a 40uF 25V capacitor.
i read a thread on the beocentral website saying that because these speakers are probably 30 years old the caps would probably be in poor condition. supposedly this manifests as poor high frequency reproduction. the caps that it came with were never regarded as being very good.
Thank you for all your help.
