The horizontal control on my Tektronix 465 is busted. Well, the coarse control works fine, but the fine control does not. I'm hoping someone can source me a replacement. It's part number 311-1430-00; Bourns calls 82C2AK32BA0005. This is one of the few pots on the 'scope that is directly mounted on the panel. It has 1/4" bushing but I would be willing to drill out to 3/8" if that is what's available to me form someone on the forum.
