Hey Everyone,

Need to get some help/advise from you guys.

My PSW125 was out of order. It is now buzz for a few seconds when you connect to the power. After that I can still hear some noise without connecting to any audio source intermittently.

If connect it to a audio source, it generates distortion sound with extremely low volume.

I have recorded the sound and uploaded it into Youtube.
Please see the link below.

Woofer was measured by a digital Multi-meter - It shows 4 ohm consistently.

1) Is the issue on Amp or Woofer?
2) If the problem is on Amp, would capacitor change solve the issue?

Any comment are welcome!
Thanks a lot in advance!

Richard
