[george graves]

Any suggestions on a "jelly bean" 10 turn pot part number?  Any one have a favorite?

What the hell is a jelly bean pot?

Just like any other jelly bean component: a component that's very cheap and common. The term comes from the fact that real jelly beans were sold from a big jar by the pound as opposed to individually packaged and counted, because they're so cheap. A jelly bean opamp might be something like an LM358: you can find it everywhere, it's very cheap and the specs are very mediocre.

I guess this is a bit of an Americanism, since jelly beans are not native to the UK nor perhaps to other parts of the English speaking world (though I think they have lately been introduced to the UK as a non-indigenous species).

The nearest equivalent British expression would be "common or garden", or "garden variety", denoting something common, readily found and not especially exotic or expensive.

(For anyone curious, the native British jelly sweet is the jelly baby, perhaps familiar to anyone who remembers Tom Baker's Doctor...)

I think the Vishay pots have better temperature stability (ppm) but, the Bourns 3590 pots are also decent and pretty cheap (Relatively speaking).

It's not cheap though. It depends on the original poster's budget.

Is there any decent ten turn pot that that's really cheap? I would expect the manufacturing to be fairly expensive because of the relatively complex mechanical construction (compared to a basic single turn pot). I've seen plenty of cheap multiturn trimmers, but not pots.

How about mechanically connecting a big knob to a multi-turn trimmer?

That would work, but don't expect them to survive many rotations. They're usually only designed to be adjusted maybe a hundred times, especially the cheap ones.
