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.
Wirelessly connects nets on schematic. Used to organize schematics and separate functional blocks. To wirelessly connect net portals, give them same designator. #portal
