Re: Polk Audio PSW 110 subwoofer

Wow thanks a million for replying on my message,have you able to check or measure the correct supply voltages when you were able to restore your own unit. I wanted to know the supply voltages for the preamp and to the main output amp if possible.Thanks really for your time and effort.More power to you and God bless

Re: Polk Audio PSW 110 subwoofer

I'm servicing the same model, and unfortunately fatal power supply failure happened on my unit. And I need badly the identification of the burned components to be able to restore the unit effectively.I'm hoping Mr.franksub can tell me the exact components I need to know and replace. Q12(H28), the resisitors and maybe capacitors connected to it under the solder side of the board. And also the DC supply voltages on the secondary of the switching transformer that is the +VCC and maybe -VCC supplying the preamp section and the main output amplifier.Thank...
