Good source for 100 ohm dual gang potentiometers
bimm25e:
I need to wire a stereo volume knob. Needs to be a 100ohm potentiometer. The only 100 ohm dual gang potentiometers i can find are like $60! Tons of cheap 1k ohm and 100k ohm but anyone onow where i could get an affordable 100 ohm? Hoping to avoid witing seperate L/R pots but thats the fall back right now as i can do it that way for about $20.
Zebidee:
100R seems very low for a volume pot, might be why you are having trouble finding it in a double-gang.
I'm not really an audiophile and don't know what you're trying to do - but I'd normally use say 50K or even 100K in my cab volume controls.
You should also consider that pots typically come with either linear taper or audio (log) taper. There are also anti-log taper types. This is because human hearing response to changes in volume is not linear.
Also, because most modern log/antilog taper pots are actually pretty crap (log curve is simply approximated by using two linear tapers), It is possible, perhaps preferable, to "fake" your own log/antilog pots from linear taper pots. This way you can even experiment with what works best for your situation.
Here's how I did it for my magenta Aussie lowboy

Point blank schematic says 100 ohm
Zebidee:
I don't know what "Point Blank" is, but commercial product schematics often include bespoke components that cost them cents to make/buy in bulk.

I should have just bought the expensive one
