Hi Klaus,
:thumbsup:
Super, thank you, a very helpful, informative answer (I have run out of helped me votes today, sorry - tomorrow). Could you explain 1/x in other words, please, not understanding what that means in practical terms. Does that mean logarithmic behaviour, as in a curve?
Depending on needs, B is the least bad choice (for me) by the sounds of it. Definitely don't want higher power dissipation in the pot, if avoidable. I see trimpots as a necessary evil, not a component of choice.
Thanks very much!
