PSW 505 - Where's the fuse?

Hello all,

My PSw 505 just quit working yesterday and I want to see if the fuse is the problem, but I can't find it. Can anyone direct me to where it is? I've attached a picture of my innards, thanks.

    Welcome to Club Polk!

    Isn't the fuse on the 505 accessible from the "outside"? A plastic flap under the power cord slot. Take a look back there and figure out how to pull out the flap.

  • I'm having the same problem. I have power, but no sound from the woofer. The 'flap' is hard plastic & is non negotiable.

    Check your signal source first, then toggle the auto sense switch to the "on" position. The light on the amp should go green.
