I asked a similar question a few days ago which I got my answer to, but I'm asking a new question now which is unrelated. I'm thinking of buying this audio amplifier: http://www.ebay.com/itm/191879583686 It has a dual gang potentiometer with 6 pins that I believe is acting as a voltage divider, which I want to replace with a wheel potentiometer. The only wheel pots that I believe to exist are 3 pin and 5 pin. If I used the 3 pins, I would have to use two of them (which I don't want). I'm not sure how the 5 pin ones work though, or whether or not it could be replace with the dual gang 6 pin pot. The wheel I'm looking at is this one: http://www.ebay.com/itm/122360414148 It says its a dual dial, though I'm not sure if that's the same as a dual gang. If it is, why does this one only have 5 and how could I replace the 6?
