Cmoy Panel Components Confusion...

I'm beyond confused with the wiring of panel components for my Cmoy, after searching around for an hour or so, and looking at all the cmoy **** I could find, I am still confused about now to wire the thing up.

I've made a little drawing with how I think I should wire it all up, but I think I have the volume pot in the wrong place. Tell me what you think:

Yes, the pot looks a little unhappy there. You don't connect the input jack directly to the board, but to one end of the pot. Then you connect the pot's wiper to the input pin on the board. The other end of the pot goes to ground. So the pot has 6 connections:
-input l/r (to the input jack)
-output l/r (to the board inputs)
-ground l/r (to circuit ground)

OK, lets see if I have this straight: I connect the switch like I thought, and the output jack to the board like I thought, but I connect the input and pot differently, I dont know much about the electrical diagram you made, but from what I can tell, the input jack goes through the pot before it gets to the board. I've heard that a pot is like 2 resistors, so I think that's why there are 2 resittory looking things in the diagram, but I don't know how I'd wire it up, my pot has 6 pins.


Edit: I think I need a diagram of the pot before I continue. Does ant part of the input jack wire directly to the board, or is it all through the pot?

Which pot are you using?

If its the Panasonic pot recommended by Tangent,

Good qustion! Let me check.

5 min later...

Here we go: A horizontal, 12mm, 10Kohm pot, part no. P2U4103 @ digi-key.

Edit: OOOH! I think I found it: Here, link to PDF

Thanks a heap, I hope this works!

From what JMT said about my pot pins, assuming it's correct:

1) L - output
2) Ground
3) Ground
4) R - output
5) R - input
6) L - input

Is this correct?:

1) L - output (pin on output jack?)
2) Ground (on board)
3) Ground (on board)
4) R - output (pin on output jack?)
5) R - input (pin on output jack?)
6) L - input (pin on output jack?)

The pot "input" pins are connected to your your source (input jack).

The pot "output" pins are connected to the
input pads of the amp.

The pot ground pins are connected to amp ground.
Also make sure your input jack ground
is connected to the amp ground.

I see, he said "input" and "output" with respect to the pot. So the "input" on the pot comes from the pins on the input jack, and the "output" pins on the pot go to the "input" spots on the board?
