Altec Lansing subwoofer died

Archived from groups: alt.sys.pc-clone.dell (More info?)

Hi Folks

I have a Dimension 8250 which came with the Altec Lansing ADA995 subwoofer
and 5 speakers. Today, the subwoofer died with a big pop. Having a peek
inside, I see that there is a capacitor across the incoming power supply.
That has exploded :(

I'm trying to find out what I should use as a replacement. Does anyone have
any circuit diagrams or have any idea what I should use?
On the disc capacitor I can see that it says MDC Z271 75UL ... but I can't
work out what they mean

Thanks in advance!

    I doubt very much they would tell me .. or even know themselves. That sort
    of detailed information isn't available to helpdesk / support staff. They
    would just tell me to send it in for service... and I'd be financially
    raped.

    Gari -

    You could try nosing around some of your local audio or electronics shops
    that do repair. Guessing that wouldn't be cheap, but is an option.

    Secondly, Altec likely won't be much help as they don't support the
    Dell-branded versions of their speakers. There may be retail versions of A/L
    speakers that are a close match, but there are usually some significant
    differences.

    Lastly, you might not be interested but there are some available on ebay.
    Might be an option after considering costs of the other options:

    Good luck.

  7. the reason it blown was due to the fact they have no manual volume control on them so they are constantly pushing out 200 wats peak power and this is a BIG fire hazard that's the reason why it popped! This happend to me so i took the amplifier out and replaced it with another one with a varible volume control then it was fine..
  8. I have a potentially damaged altec lansig 995 sub, does anyone think it easy modifyable to use it as a hifi sub on its own?
  9. MDC Z271 75UL is not capacitor. It is the Varistor (with maximum operating AC voltage- 270 V).
    It carries out a role of protection against an overvoltage. (It is the "Surge Arrestor").
