The "Breakaway" board with all controls is hidden by chassis lip above but shown in here in
Figure 1b.
Figure 1b – Orientation of Breakaway Board
On the Breakaway board, there are 3 thru-hole points (A, B, C, in photo below) of contact for R84
(GAIN) and R85 (VOLUME 1). The blue wires and jumpers come later so ignore them for now.
After making the following cuts in the traces, the trace should be checked with an ohm-meter to
verify it is indeed "open"; if the meter indicates zero ohms, the trace hasn't been completely cut.
FOR R85 ONLY (the left-most control next to
INPUT jack when oriented as in Figure 1): cut
PCB trace where circled, between R85
terminal A and the via (thru-hole in PCB) as
shown in Figure 2.
from P5 and the DSP board and set aside (it is no longer needed).
