You are making a volume control to lower the volume of the amplifier that is basically too loud. This might be the one for the bass, or possibly the one for the high frequencies. In any event, the volume control would be inserted before the input of whichever amp needs to be turned down in order to achiever proper level balance between the highs and lows. The neat thing about making the level controls in a separate box is that they can be used for either amplifier.

In the remote possiblilty that your tube and solid state amps have identical gains, you would not need the level controls at all, but I am pretty sure you will.

In the unlikely event that you can't find the proper way to wire the level controls, here it is:

Hold the control with the shaft facing you, and the three terminals pointing down. As you look at the control, the terminal on the right (the clockwise direction of rotation of the control) is the input side which goes to the 950 or whatever your source component is. The center terminal goes to the input to your power amps, and the left terminal gets the shield wire from both the input and output interconnects.
