I'm cutting the board to build a Mutron III and it calls for a 150k Log pot. What would be the best way to make something close? Use a 250k with a resistor?
I think maybe the most accurate way to do it would be to take a 100K log dual gang pot and a 50K dual gang pot. Open them up and swap the top wafers.
Now each pot has a 100K log wafer and a 50K wafer. Wire the two elements of each dual pot in series with each other making each pot like a single 150K log
I read about this here and have not tried it myself so I can’t comment on how easy it is to modify the pots but I like the idea because it should have a predictable taper and resistance
Speaking of swapping wafers, all the pots I buy you have to break the washer in to pieces to remove the wafer cos the washer is stamped in by the shaft. Anyone else noticed that? Is there a way around this?
