    Default Polk PSW 120 stopped !

    Hi,

    I have a polk psw 120 that i notice had stopped working. the green light won't come on. I took off the screws, removed the panel and found a fuse. the fuse does not look blown, however when i put foil around the fuse to test, the light does come on but the subwoofer makes a squeeling sound.

    i let that continue only a few seconds.

    I would like to try a new fuse first, where would one find such a fuse and what size is it. it is very hard to read.

    Secondly, could that howling be a bad capacitor and are replacements available. its a great little sub and would be a shame to not be able to continue to use.

    Hello sbarreth,
    Welcome to Polk's forum. In all likelihood there is a problem with the bass amplifier and there's no need to try a replacement fuse. The best place to begin solving the problem would be with Polk's CS department at: 1-800-377-7655 or email at: polkcs@polkaudio.com.
    Regards, Ken

    So is this common for the amp to fail. It IS about 15 years old. Is it possible parts are available and would you happen to know the fuse type/size?

    Hello, it is a 0.6Ampere 250Volt time delay (also called a "slow blow") 1/4" x 1 1/4" fuse. Polk CS can best advise on parts availability.
    Regards, Ken
