Hello, quick and stupid question here. I have the Pass board, and the recommended PEC 25K linear pots. They are installed upside down, so that the solder tabs stick up.
Looking at the board, each channel shows cw,ccw and w. Which hole goes to which tab? There are no markings on the PEC pot or tabs that I can see. Thanks for any help on this simple question. Now for a really stupid question. What does cw,ccw and w stand for? Only thing I can think of is clockwise, counter clockwise, and whatever w stands for. There.

Wiper. The connection to the moving contact
Gottcha. Thanks for the hyper fast answer! You wont believe how long I thought about it before I asked this question and exposed my total ignorance on the world wide web.
Can you tell me which is the wiper? I assume the one (usually center) that varies as the pot is turned? If so, does it matter which the other 2 are connected to as long as both pots are wired the same, or it isnt that simple?Russellc

Welcome to the club, I had to ask a friend of mine...
With two pots, how can they not? Well as long as you adjust one channel or the other to match. I'll set them where the volume is nice for listening, match the levels, then loosen the set screws and move the knobs to the straight up position. If I want it a little louder, turn them a little up, if quieter levels are called for, turn them down a little.
Eventually I will try different potds here, something a little more refined, but for now, the Pass specified PEC pots are being used. Hard to go wrong a 10 bucks a pop! ( At least price-wise anyway ).

yes, I figured better to just ask this instead of hooking it up wrong and having to show a pic of what I did!

This case was made by member Westend, who had offered his services and does so fairly. The side are aluminum extrusions cut to length, driilled and tapped for the front and rear panels, which are 1/8 inch aluminum, 6061 I believe. The top and bottom are drilled and srewed into the little thresded devices that are in the top and bottom tracks of the extrusion.
Contact Westend for details,

Nice one Russell
Thanks guys, much appreciated! Westend should get credit for the box. Wait till you see the F-5 box he made from 1/8 aluminum, 1/4 inch for the faceplate, very nice, extremely strong and reasonable as well!
