dual concentric pots

Does anyone know of a source of dual pots with concentric shafts (as
formerly used on, e.g., car radios for volume and tone controls)?

I've looked at Alpha [Taiwan], ALPS, and Piher. Such pots show in their
on-line catalog pages, but not as a stocked item at Digikey, Mouser,
etc. Hence, the real question becomes, does anyone know of a source of
dual pots with concentric shafts that are available from stock?

Preferred values are 25k each section (50k could be used).

Addendum: Does ALPS actually have any sales reps in the US, or do they
do all technical consultation directly with factory reps?

Google on "dual-ganged pots" and you'll get a raft of responses.

** Absolute bullshit.

Plus the OP wants "dual concentric" pots.

A different and much rarer animal entirely.

Good luck... I've never found any either. Not only do Mouser not stock
them, but they've been unresponsive to questions like "what would it cost to
get 5000 of these."

Your next challenge will be to find knobs that work with the pots you find.
Heh.

If you do find some, post here, or perhaps sci.electronics.components - I'd
love to know the answer.

Oh, yeah -- the knobs. I forgot about those. One more challenge to
mess with.

OK, will do.

Talking to Alps is notoriously difficult.

Concentric pots are a special order item these days.

AB's 'mod pots' of old enabled you to build them as a kit IIRC but I'm not sure
they're even still available. You can bet they'll be costly.

Maybe try Bourns ? Vishay even perhaps ?

Scott Dorsey on rec.audio.pro might be able to help.

What's the application ?

This is more of a consumer electronic item. I have had better luck
actually buying such things in Japan, Taiwan or China.

Last I talked to them, no. They were only interested in selling to
automotive type customers and gave us an FU price *and* MOQ.

Checked Bourns and Vishay. Nope. I'll check on rec.audio.pro.

Ooo! That (potentiometers.com) does look promising. Thanks! And yes,
mortal that I am, I do believe I can cross ALPS off my list.

http://www.radiodaze.com/ has some dual concentric pots listed. Look in the
Components/Potentiometers links. Don't see a 25K pot, but there is a 50K audio
taper unit listed for $2.49 US Cheers!!!! -- Dave M MasonDG44 at comcast dot net (Just substitute the appropriate characters in the address) Some days you're the dog, some days the hydrant.

Looks like those are just dual-ganged, not dual-concentric. But thanks
for looking around for a source.

Skycraft has absolutely no idea what they have in those piles of old
parts. It is a family owned business and not one person there has any
idea of what electronics is or what the parts are really worth. A quick
look at their website will show you what I mean.

Oh come on Mike. Everyone in the family knows where every part is in
the store and what it costs! You ask one of the girls at the counter
"Where are the double ganged and concentric pots?' They say "Aisle
three!' They price the used stuff at 'about half of retail'. Just being
able to look at the stuff is better than picking it from a picture on a
computer. I've been going there every weekend since '74. You need to go
every week to catch the interesting stuff and good deals.

Its not worth spending a whole day making the trip there and back
(Over three hours each way) on the off chance that they actually got in
something worthwhile. Its too bad that the other surplus stores closed,
and that "The Electronic Barn" went to stereo crap. I have almost as
much stuff stashed here as they do, anyway. I grew up about an hour's
drive from Mendelson's in Dayton, Ohio. The stuff was five to ten cents
on the dollar for new parts, and the junk was sold by the pound. they
had two floors of a six & a half story building open to the public, and
it was a full city block, with another city block of parking, just
across the street. Skycraft bragged to me that they did $1,000,000 in sales one year. Mendelson's did over 100 times that in the same year. Then there was Fair Radio, in Lima Ohio. As far as Skycraft, I used to sell him truckloads of parts and hardware when I worked for Sonnetec systems in Altamonte Springs. The guy who owned Skycraft was a real thief. He would tell my boss, I can only give you 50 cents each for these contactors, I can only get a couple dollars for them in the store. I smiled and asked, Then why are they priced at$90 in your store? Either give me the $5 each, or put them back on the shelves. he never bought anything expensive, unless he had someone waiting for it. He left two truckloads of stuff piled on the floor that day and called my boss to tell me he wouldn't ever come back, or buy anything from us, again. A week later he was back with$2500 in cash.

I had a ball just wandering through his store with him following me,
trying not to be seen. I would find something that had a decent price
that i could use. If I didn't buy the whole lot, he pulled them off the
shelf and marked the price way up.

BTW: Have you ever been to Acme Industrial Surplus?

The last time i bought dual concentric (50k linear) they were about \$10
each, in the 1970's. I pinched the tangs a bit to make them "clucthed".
