I built a SCR throtlte power supply for my model railroad quite a while ago and I am now experiencing a problem with it. I think I narrowed it down to a potentiometer shorting out. My problem is not being able to find or replace with an equivelant or near equivelant pot. Radio Shack doesn't carry what I need and I can't seem to find a hobby supply specializing in electronics. I am in need of a 250 Ohm linear taper pot (the original is:Mallory VW-250). I am hoping to find a replacement or a different pot which will work. Any advice is appreciated.
