Hi Jazz,

I'm pretty sure the noise stemmed from just a rats nest of unshielded cable. The clue was that it was worse when the vacuum was on. It seemed to make sense to replace all the cabling in one go since that job had to be done anyway.

Whereas I would totally agree with the "do it right first time" school of thought, I think its right to keep in mind that not everybody has the same level of experience. For me on my initial build, it never even crossed my mind that unshielded cable would be a bad idea. I just wanted to get it up and running. I know now and in future I will not make that mistake again. To me, the real fool is the one who repeats a mistake.

Cheers,

Dave.
