    I want to replace a trimpot like the blue guyon the right with a standard alpha on the left. before i wire anything up, i wanted to be sure that i was correct as to what lugs on the alpha correspond with the lugs that are on the original trimpot. based off the photo below, am i correct?

    Yes, that's correct. A-C is the fixed resistance of the device, B is the wiper/divider. Easy enough to verify with a meter.

    Are you sure you want to do this? The blue trim-pot is a multi-turn and the other one is less than a 360° turn from min to max. Multi-turn pots are usually used where the precision is needed. They're more expensive than a standard trim-pot, so manufacturers don't use them unless they have to.
