I'll give you a dollar for all of them.

Pig in a poke, eh? "If you can guess how many chickens I've got

Why din'tcha say "I'll give you 100 cents for them" and give the

a
conniption fit when he thought you meant dollars... Or offer him
forty
thousand quatloos.

I've got a bunch of 100k full-size pots with a SPST pn/off switch
on
the
back that I'll trade for them. I have a couple bags, must be over
a
hundred. Problem is they're lin, not log taper. What kind of
circuit
uses a lin pot with an on/off switch? Tone control? Squelch?
What
else?

Power supply!

I've been noticing that all the HP PSes, even the cheap ones, use
wirewound pots for the V and I controls. They even specify the PPM
tempco. Some use the three turn precision pots, better ones use the
ten-turn pots. I think it makes a great deal of diff in the stability
and repeatability of the settings.

The pots I have are all carbon, and the value is a bit high for most
linear PSes, such as a LM317, where 5 or 10k is about as high as
you'll
ever need.

I dood a google search for 100k pot schematic, and the first hit I got
was an old favorite that I'd almost completely forgotten about.
Heh-heh. But times have changed...

But in this same search I found a simple way to change the 100k lin pot
to log.
