DOMC:
anyone know a good place to get precision pots for "thing" i am building a prototype of?

Thomas W. Bethel:
Stepped or no steps?

Lots of places...

It all depends on what you want to spend and the precision you desire.

Define 'precision'.

On recent 'things' I've been tinkering with ... I'd given thoughts to Veneer dials.. .


Anyone know of good sources for that. seems like it might be a good way to get more fine-tuning, and better recall ability without the expense of stepped switches.. (however when I priced it out, it wasn't that much different).. Just need to find a good source.

any drawbacks to using them?



  Also ... seems like we're only a few years away from good availability of digitally controlled analog components... seems like that would take away the need for expensive mechanical processes for precision gains, etc ... the ULN8 uses them, and I've heard of other prototypes doing that kind of thing. excellent L/R matching, very fine tuned (0.1dB, etc ..) Anyone have any knowledge to share about using those options?

Mouser and Digikey both carry multi-turn pots and Vernier dials for them. You can get good precision but cranking the pot five or ten times around for a setting kinda sucks for daily use.
