Quote Martin Walker:
It's certainly worth doing the resistor caboodle, to break any ground loops, but to be honest I've never fitted the capacitors as well, and (touch wood) haven't have any RF interference as a result.
Of course, your mileage may vary, but with such short leads I'd be surprised if you didn't get away with it
Thanks, Martin! Would something like this be okay? http://www.ebay.co.uk/itm/360208771993?ssPageName=STRK:MEWAX:IT&_trksid=p3 984.m1423.l2649
They look rather big to fit into a TS connector but can I just remove the long spiky bits? (I really wish I could remember more electronics from school!)
