I think I found the answer and a diagram.
"For those who wish to change the pots for fixed resistors, here are resistor values to produce required gain. Gain is listed in dB: To change gain potentiometer to a fixed resistor, you would connect a fixed resistor between the yellow and black wires on the gain controls (of course, remove the gain pots). Leave the red wire disconnected.
Use high quality 1% resistors: 1/2 watt is sufficient.
560 Ohm = 31 dB
1K = 30 dB
2.2K = 27 dB
5.2K = 23 dB
6.2K = 18 dB
7.5K = 16 dB
I hope this is of some help. Please feel free to post this on the forums if it will help others. On my personal systems here, I use the same pots that come with the kits."
My diagram wouldn't upload but I found it here:

My colors are different, yellow is the same, but the black on the diagram is white on mine, and the red on the diagram is blue on mine.
All I need to do is put a resistor between the yellow and white, and leave blue open.
Now I just need to decide if I want to use a Vishay VAR "naked", or a Shinko Tantalum resistor?
