Ah, now I see... thanks!
From that diagram, it looks like pin 6 and a resistor are needed for b&w mode? Also, just curious, but is the 1K to the black triangle from the 6/9/cap junction needed for anything? As I recall from my stereo mod, it used some resistors from the [12|13]/cap junction that went to +5V.
Still, thanks for the help!
