5) Using a short piece of wire-wrap wire connect the each pot's #3 lead to the IC's #4 pin (-
15V).
6) Connect a 90.1K resistor between pin #2 of the IC and #2 lead of the pot for each.
Power up the boardset. Connect a scope to the RED color output on connector P2 pin 6. Note: all
ODD numbered pins are GND. Adjust the pot attached to U29 so that the signal level swings
between 0 volts and 4 volts. Repeat the adjustment for GREEN (U14) and BLUE (U15).
* Modification complete *
CAVEAT! - I have done this modification to two boardsets so far and got the expected results.
However, since electronics is three parts Black Magic, two parts blood sacrifice and one part skill, I
cannot take responsibility for what occurs to your board should you make this modification. All I
can say is 'It worked for me'."
