I’ll update the PCB layout to reflect the safer isolated-jack redesign: arrange the four jacks, DPDT switch, and two speaker connections in a clear jack-plate style layout, then check placement.
The existing PCB components were mostly off the board area. I’m moving them into a 160×100 mm jack-plate style layout: stereo jacks left, mono in/thru right, DPDT centered, speaker terminals above.
Updated the PCB layout into a readable jack-plate arrangement on the 160×100 mm board.
Open items:
J1/J2 are labeled as dual-switching isolated jack positions, but the exact 6-lug dual-switch jack footprint is not in the Flux library yet.
DRC still reports airwires because I placed the components but did not route copper traces; for this cabinet, the point-to-point wiring document remains the build reference.
Layout now has:
J1 Left Dual-Switch and J2 Right Dual-Switch on the left side.
SW1 Series/Parallel centered.
J3 Mono In and J4 Mono Thru on the right side.
SPK1/SPK2 speaker connections above.
Silkscreen notes for the DPDT switch contact behavior.
