    The expense may be worth it is not necessary to change all the capacitors with expensive ones. It is important to change the series capacitors in tweeter and midrange lines while the others may be substituted with good standard capacitors with fitted value according to the original ones.

    Look like standard polyester film caps to me. I've replaced the NP electrolytics in my JBL L-222's with standard value film caps no problems. Had to parallel some to get the value needed. The problem is I think like you have shown, high uF value sized films are really big! Thanks nick for the great videos.

      Hi Danish, yes they're almost certainly "poly put the kettle on" as dave on eevblog calls them! The problem with their size is because they're rated at 250 volts, which is way higher than I needed. But cost was an issue so I went for these because they were relatively cheap compared to lower voltage ones I could have got in this country. Anyway they fit in the cabinet no problem. thanks for watching, nick

    Those are great speakers Nick and well worth the effort. I’m sure you have given them a new lease of life and sorry for butting in on your capacitor shopping. Cheers Graham

      What capacitor shopping Graham? That was months ago! I must say those Chinese capacitors were excellent quality. They're lovely speakers, got them for about £50 from Bristol(very cheap). Had to sand down & varnish the veneer.
      Cheers

      Hi Mike, thanks for your kind words.
      Try this link for the capacitor seller on ebay.
      www.ebay.co.uk/itm/175325552967?var=474554856062
      That's for the 47uf but they do many other values.
      I highly recommend them. If the link doesn't work I'll email you.
      Best wishes Nick

    I moved from wales to puerto rico. Anything from the uk, even a cap would include a standard 45quid postal cost😂 so yeah im shopping china with you sadly. Tories cutting off world trade i guess. used to be a pound or two a couple of years ago.

    please tell me how to set my multimeter to test the capacitors...also can i test them while on the crossover and when they are not on the crossover?...
    I am new to using a multimeter...
    thanks

      @ptronix  7 місяців тому +2

      Hi Brian, if your meter has a capacitor range you can measure them, but you would need to disconnect one end as other parts in the circuit will influence the reading.
      This is only a basic test, it will not tell you the 'esr' effective series resistance, which will go high as a capacitor ages and becomes more like a resistor. The other problem with capacitors is they go leaky as they get older and start to conduct DC. So capacitor testing is a complex business. Hope that all makes sense. You could always send it to me for testing!

    Not worth the effort.. Not brilliant compared to larger Tannoys they are dated.... Celestions 400 GBP. Tannoys 2 to 4 grand at least. For people who can't afford modern speakers so they can convince themselves that they r at least as good as modern equivalents😂

      Why did u bother recapping already absolutely excellent sounding speakers .Was it because u really don't have such a high opinion of them.. Because they have a dated PA Speaker type of sound etc
