This video will show the repair of three different problem areas found in the Polk PSW505 that was presented to me.
In a previous career I spent 25 years in the high-end audio sales and service business. A friend of mine asked me to take a look at his Polk PSW505 sub woofer that was generating loud noises and powering off. After doing a bit of research on the internet for a quick fix I found that a lot of people out there were having a similar problem. The factory was no help in providing a schematic or offering the proper tech support that I was used to receiving "back in the day". Be patient! This will probably be not be a quick fix, but it can be done.
I hope this helps!
Regards,
Dennis
