Ian,
Thanks for the tip mate, I'm not being a scrooge about not buying the Starcom one it's just that I really like to have a go at things myself. My only problem with this is I wouldn't know what a 10k pot linear would look like. I'm going into Maplins tomorrow and looking on their website I see they do a whole long list of these things. In a word, what do I look or ask for( bearing in mind, some of the lads in our store would have a job finding the door without a sign over it) and what sort of cable do I need to make it up?
Sorry for all the questions, I can just see educated going or maybe even don't bother
