With the cover off, observe the Oscillator board. On the right side of the board, there
will be a matrix of trimpots. If you see two columns of three trimpots, you have the
second version. If you see four columns of three trimpots, you have the third version.
TUNING PROCEDURE, SECOND VERSION
This is the board that is in my Minimoog. I modified the procedure slightly because it tunes it
better.
The arrangement of the trimpots is as follows: each row pertains to each oscillator, the top is
OSC1, middle is OSC2, bottom is OSC3. The trimpot on the right is RANGE, the one on the
left is SCALE. Near the bottom is a lone trimpot, this is the OCTAVE trimpot.
Only the RANGE and SCALE trimpots are accessable through the access holes on the rear
cover.
