Its all there.
Good chance to correct my past version that had a typo and up[date the pot
The pinouts are:
Pin 1 mic in +
Pin 2 mic in -
(Pins 3 & 4 - ignore, they are jumpered to pins 1 & 2
for convenience in case you wanted to put filters before the inputs, you could
put resistors between
the pin 3 out and the pin 1 in for example)
Pin 9 and 10 Feedback loop for gain control. My brother and I used 1 meg
pots, but Oliver Archut at Tab Funkenwerks recommended "a 500k linear pot wired
in reverse between pins 9 &10 with a 500k resistor across pins 9 &10 as well."
Pins 13 & 14 output 3 unbalanced (but we haven't tried it )
Pins 19 + & 20 - balanced output 1 (your main outs)
pin 17 with 21
pin 22 with 23
pin 24 with 27
Pin 29 0 volts (circuit ground)
pin 30 chassis ground
pin 31 + 24 volts
pins 25 & 26 are schema'ed as balanced output 2, but maybe only for the 672/2
which had 2 balanced out.
