[sdiy] beginner SDIY... larger Pot values & carbon VS. Metal film resistors

Hi Todd,
glad to see you on the other side.

It depends if you're using it as a variable resistor or a voltage
divider. If only two leads are connected then it's a variable resistor
and you'll get all the range of the 50k pot in half the turn, and then
'more' as you keep turning.
If it's a voltage divider (this can be hinted by three leads
connected) then I can't imagine it working any differently, but there
could be some esoteric applications of a potentiometer - if the
circuit is drawing current through it.

All depends on what you're using them for.
If it's stuff like filter feedback or an oscillator core, I wouldn't
risk problems.
