Hey all, I have some step up/down converters which use 10 turn 10k trim pots, however I have some nice "precision" (5%) pots from an old Tektronix scope which are 50k, and would like to use those instead because they are a) easy to put in a case and access and b) have the nice double dial sort of design.
I am trying to figure out how I could substitute the 10k pot with these 50k pots and keep the same functionality. I imagine some op-amp circuit could do it, I'd like to do it with passive stuff that I might have lying around. Any tips? I'm thinking perhaps a resistor would be able to do it, though not 100% sure that might just work for increasing it.
edit: hmm, from what I see adding a resistor in parallel will decrease the value, I'll grab some and see how that works out.
