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.
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.
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
Hi John, I thought I did not have any material of the modifications but it turned out I had so I wrote a new blog post: http://jussikilpelainen.kapsi.fi/wordpress/?p=394
