DPDT potentiometer wattage question

Post by jlatrace »

I am having trouble finding 1/2 watt push pull DPDT potentiometers to use in the treble and mid section of a D-clone I am building. My research here uncovered a 16mm pot rated at .125 watts that several folks recommend (Mouser 313-1600F).


Question - Do I need to be concerned if I use the pot rated at .125 watts in the treble and mid pot section?

No concern at all since there is practically no current flowing thru the pot.

I was looking for a 250K Linear DPDT pot the other day and found this at Torres.

I had one here I think it's a Dimarzio pot.
The bushing is tiny and the shaft was smaller than 1/4".

I put it in my D amp because I wanted to try the mid-boost without drilling holes.

Not sure if the Torres pot is an Alpha but it most likely is.

Looks like Mouser is cheaper, so if you have other things to buy that would be the way to go.

Tubes and More has a 1/4W here.

You can find a CTS 1378149 here. Weber also has the same pot on their Pot order form page. Look for part# wp105A-PPSW. I'm not sure of the Wattage rating of the CTS, though.

I used a guitar type PP pot in my P1 eXtreme for a Volume w/ PULL Clean switch. The only problem is it has a totally different feel than the other pots - much less rotational friction. YMMV.
