Stereo volume Potentiometer

hotscot · 20th January 2007, 10:25 PM

I bought a pot at Radio Shack.

It has two sets of 3 pins on it. Do they all follow the same contact numbering conventions ie Pin 3 at the left Pin 1 at the right when facing them?

It's unnumbered on the body.

I used the same pot on my rebox of the SI T-Amp. Looking at the pot from the front (adjustment knob side) the front row of pins are for one channel and the back for the second channel. The pins on the left connect to the source (RCA input jacks), the middle go to the input on your PCB, and the right pins are for ground. Follow the attached link to input mods and you will find a picture of the pot connections.

Both channels in the POT will have the same pin-out. The middle pin is the wiper. The other two will determine whether you are going to use clockwise or counter-clockwise operation. It's easiest to just use a meter to test it and decide which way you'd like it to work.

Hope you bought an audio or log taper pot, otherwise the loudness with rotation will be realy wierd.
