Hi all,

I have a set of Videologic Digitheatre DTS speakers, which have the amp integrated into the sub. Recently a transformer in the sub has started to make quite a loud buzzing noise which is starting to get distracting.
My question is: would it be possible to replace the offending hardware?

There seem to be two transformers in the sub, a larger one and a smaller one, I think its the larger one that's making the noise, but i may just replace both if possible. How do i go about finding a model number or something to I.D them? I'm pretty experienced with soldering so that aspect shouldn't be a problem.

Many Thanks

Mikey
 
they were around £200-£300 i cant remember exactly, either way i would like to repair them. I have a multimeter what do you need me to test?
 
buzzing sounds like its at 50hz, just played a 50hz sine signal and they were the same pitch, will try n get pics asap
