[QUOTE="Phoenix, post: 493153, member: 8133"] Assuming a relativly high impedance input, then surely all you need is a 10v supply and something like a 10k pot with the ends across the poles of the supply and the wiper as your output. (remember 0v needs to be linked to the grounds associated with the inputs) If you don't need to get right up to 10v, you could use a smoke detector battery. If you need a true 10v supply as as base, then start with a 12v dc wall wart adapater, and feed it through one of the LM2596 voltage regulator modules you can get online, use your multimeter to set it to exactly 10v, then use that as your supply for your pot [/QUOTE]
