Default dual gang audio pots and where to find them

I had no idea these parts were so hard to find. When I built my amp, I used a single gang pot for each channel's volume control. It got to be kind of a pain tweaking the dual volume controls until both channels were equally loud. Radio Shack has a 100k dual pot but that's too high a resistance for my application. Where is a good place to get a 10k dual gang pot?

You could try mouser.com part# 313-2420F-10K, it's a 24mm Alpha brand. I bought a couple of this style a little while back, seem to be pretty good construction.

Default Thanks for the quick response!

THank you all. That was very helpful. Since I already have a hole drilled in the chassis front panel, I thought I'd put a balance control in the hole. Anyone know how to wire one of these and can I use one of my original pots to do it?

Default Dual gang on/off?

Does anyone know where I could get a small dual gang on/off switch so I can turn my stereo circuit on at low level nd then keep turning to raise the volume?

if you look in Bourns or Vishay spec sheet you can find a letter for the type with switch function
you can choose a linear pot and mount a resistor from the variable pin to ground(1/5-1/10 of the pot value)

I hear ya BUT that raises my eyebrows. I like to use the volume control as little as possible to reduce wear 'and tear' - it is mechanical, it does [usually] wear out, it will [usually] make you regret going that route sometime in the not very distant future - it has for me . If at all possible, I think it is much better to have a separate on/off switch.

This is for a project that has size restrictions, so big bulky pots and switches are not ideal.

I just want something like this:

New 500K Linear Taper Pot on Off SPST Switch 3A 125V A | eBay

but dual gang.

Thanks

hmm, for guitar there are some where a switch function is activated by pulling the shaft out
but reminds me...you need a spec sheet to make sure its fit for mains voltage, and not just a signal switch
may be just for small signal

you can get small and neat push bottom switches for mains voltage
or simply just mount the switch on back panel
thats where the mains voltage comes in anyway

this trash box I found already had both a switch and cable plug ...cost free
