I read that System 11 audio boards have different resistor values to balance out sounds on various games and that swapping the boards around these resistors may require changing.

Anyone know where a list of which of these resistors and their values may be for various games?

Ok. I have done some more research.

R13 is not listed on the WW Audio Board Assembly.

R13 is given as 1.5K Ohm in the schematic

R13 I have on the forums read is 4.99K by one account.

R13 that is in there is 4.99K (Y/Wt/Wt/Brn/Brn)

Anyone have a WW that can compare what the value of R13 is. It's just above J1 on the left.

Colour code can be deciphered here just by clicking on the number of bands and the colours:
