I'm after one, or maybe two. I'm knocking up a phono stage and need something about 50mm in diameter and black <yes, alright stop tittering at the back :) > RS, Farnell, Rapid and Maplin only go up to 32mm so if anyone had any ideas I'd be grateful. Alternatively if anyone has an old dead amp that I can scavenge I'd gladly make a small payment. ta
