Bad product design: Wharfedale DX-1

When I moved to a new apartment a few years ago I decided to get a 5.1 home theater system. Wharfedale Diamond speakers are quite nice so I decided to get Wharfedale DX-1 home theater. I have been pretty happy with it except for one major annoyance – the amplifier inside the subwoofer tends to break when I move the subwoofer for cleaning.

Broken Wharfedale DX-1 amplifier module, based on TDA7294.

I changed the TDA7294 chip the first time this happened, but now I think that I will get a class D amplifier module from China and use it instead. I will post some pictures when I complete the mod.

  1. I now have a similar problem, was this ever resolved with a mod?
    Also is there a schematic available somewhere for the DX-1 Subwoofer so that it can be repaired
