need help finding a pot
« on: April 05, 2022, 09:11:19 pm »
does anyone know where in the U.S. i can find a pot like this? Dual gang 1 meg audio with dpdt?  I have searched all day online and only in europe they have this pot will cost me $40 with shipping from them and takes a long time to receive. Many thanks to all.

Try one of the Chinese stores on eBay (or the Chinese version of eBay)

The difference between the one at AES and the one at TubeampDoctor is that the AES pot is for a PCB and the other one has terminals for soldering wires to. You could ask Alpha what their Part # is for the one with wire terminals  - they have contact info..  http://www.alpha-products.com/Potentiometers/potentiometers.html

closest I see:
https://www.electronicsurplus.com/mallory-126255-235640-potentiometer-1meg-dual

The switch on that engages when the pot is turned. I need a push pull switch

Here a couple places, maybe you can find there.

https://www.amplifiedparts.com/products/potentiometer-bourns-audio-solid-shaft-dual-mini-push-pull

https://tubedepot.com/products/alpha-16mm-audio-taper-pot-w-dpdt-push-pull-switch-7mm-bushing-pc-mount

Thanks but neither of those are dual gang 1M pots.  I guess i need to order a big box of these from Europe and start my own business..

are you repairing a piece of gear for a customer? pass that cost onto them and move along
if not, a good rule of thumb is to not build with unobtanium parts. drill another hole for a switch and be done with it

To tragichero's point. I suggest posting the application/schematic as forum members might have some clever work-arounds which would depend on what the push/pull is controlling.

My thought was . buy ten and list 8 of them on ebay or craigslist for $12+  :-)


Of course when you do that then before you sell them all AES or some other company stateside will start carrying them for $5
