My TV and it's surround sound equipment are supplied via an Eon Intelli-plug and a 4 way extension lead, this all works as one press on the remote control and it switches everything on or off, the only problem is when switching off there's a loud pop in the speakers, this presumably is from the relay coil in the plug, after a couple of attempts to cure this, a surge protected extension lead didn't help, I searched around and found an Iskra 0.047µF, 275VAC, X2 capacitor which I fitted into a 13A plug top next to the other plugs and this works fine, however after further reading it seems that I really need a snubber and that means fitting a resistor in series, this I can do if it's not too big, can anyone give me some idea of a suitable value or perhaps more importantly what wattage and voltage rating please?

Thanks

John
