3. Disconnect the stranded wire cables from J301, J303, and J325 on the Connector Board.
Note: The cables used throughout the PC3x are bundled and routed so that their locations and
destinations seem obvious. However, to avoid reversing the Bass and Treble cables when
reconnecting, mark one or both cables designating B for Bass and T for Treble.
