Subwoofer Hum

[londonbairn]

I have had subwoofer hum for a while and finally got round to tracing the driver of it. Turns out to be the Sky box due to the coaxial connections.

What is the best solution here? Is it something like AV21847 at CPC?

You sure its the coax and not the sky box psu?

Yes, I tried that hypothesis by keeping sky on and then unplugging the coax from the wall. Humming stopped straight away.
