Woburn III Speaker Problems

My Woburn III is acting up. While in AUX or RCA mode, I get a loud POP when I turn it on. Also, the sound is terriable. My Stanmore III sounds much better. It's not under warranty. Is this something I can fix myself?

Hi @craigbell48163

Best option would be to open the speaker and initially check for any leaking or bulging electrolytic capacitors on the control board and the I/O board.

Faulty capacitors can play havoc with the sound in audio equipment.

Here's a teardown video that may help.

If you do find any, their specifications are printed on the side i.e. capacitance and voltage rating. Also before removing them note the orientation of the way that they're soldered to the board as they're polarity dependent. The -ve side of the capacitor is marked on the capacitor's case with a stripe. Conversely the +ve side is usually marked on the board where they're mounted. Do not reverse then when soldering them on the board as they will blow when the power is connected or at least very soon afterwards.
