Rev0.5-110V - 110 V variant (UNTESTED)

UNTESTED. 110 V variant (original PS3116-051, 100/117 V parts): same copper as Rev0.5, fuses 0.5 A, transformer N-218C (117 V tap; 110 V is 6 % below its rating), switch SDG5P-001. Silkscreen mark PS3116-051 110V, R5 corners. See BOM-110V.md. The 230 V board is the separate release Rev0.5.

ERC 0, DRC 0 errors, 0 unconnected, schematic/board parity 0. Contains Gerber (zip), 1:1 printout (A4) and schematic PDF. Not manufactured, not tested on a unit. Mains voltage can kill. Licence: CERN-OHL-W-2.0.

Rev0.5 - 230 V (UNTESTED)

UNTESTED. 230 V variant (original PS3116-054, 220/240 V). As Rev0.4, but the silkscreen mark PS3116-054 230V is moved clear of the F4 fuse holder outline. R5 corners, RM5 screw terminals on the mains side. Tracks and part positions unchanged. The 110 V board is the separate release Rev0.5-110V.

ERC 0, DRC 0 errors, 0 unconnected, schematic/board parity 0. Contains Gerber (zip), 1:1 printout (A4) and schematic PDF. Not manufactured, not tested on a unit; dimensions derived from the component layout (±3 %). See VERIFICATION.md. Licence: CERN-OHL-W-2.0.

Rev0.4-110V - 110 V variant (UNTESTED)

UNTESTED. 110 V variant (original PS3116-051, 100/117 V parts): same copper as Rev0.4, fuses 0.5 A, transformer N-218C (117 V tap; 110 V is 6 % below its rating), switch SDG5P-001. Silkscreen mark PS3116-051 110V, R5 corners. See BOM-110V.md.

ERC 0, DRC 0 errors, 0 unconnected, schematic/board parity 0. Contains Gerber (zip), 1:1 printout (A4) and schematic PDF. Not manufactured, not tested on a unit. Mains voltage can kill. Licence: CERN-OHL-W-2.0.

Rev0.4 - 230 V, R5 corners (UNTESTED)

UNTESTED. As Rev0.3 (230 V, PS3116-054), but all board corners are rounded to R5 and the silkscreen carries the mark PS3116-054 230V. Tracks and part positions unchanged.

ERC 0, DRC 0 errors, 0 unconnected, schematic/board parity 0. Contains Gerber (zip), 1:1 printout (A4) and schematic PDF. Not manufactured, not tested on a unit; dimensions derived from the component layout (±3 %). See VERIFICATION.md. Licence: CERN-OHL-W-2.0.

Rev0.3 - RM5 screw terminals on the 230 V side (UNTESTED)

UNTESTED. As Rev0.2, but the 230 V primary side (terminals 1–9: mains, mains switch, transformer input) uses RM5.0 screw terminals (Phoenix MKDS 1,5, four blocks X1–X4) instead of solder lugs. Terminals 10–22 (low voltage) stay solder lugs. Terminal numbers are on the silkscreen.

ERC 0, DRC 0 errors, 0 unconnected. Contains Gerber (zip), 1:1 printout (A4) and schematic PDF. Not manufactured, not tested on a unit; dimensions derived from the component layout (±3 %). See VERIFICATION.md.

Rev0.2 - more spacing on the mains side (UNTESTED)

UNTESTED. As Rev0.1 (copy of the 1984–86 original), but the switched mains conductor SW_B is moved away from SW_A and from pad F1.1: SW_A/SW_B at least 5.67 mm (was 3.75 mm). Mains to low voltage unchanged above 8 mm. Circuit, parts and dimensions unchanged.

ERC 0, DRC 0 errors, 0 unconnected. Contains Gerber (zip), 1:1 printout (A4) and schematic PDF. Not manufactured, not tested on a unit; dimensions derived from the component layout (±3 %). See VERIFICATION.md.

Rev0.1 - historical 1:1 copy (UNTESTED)

UNTESTED. PS3116 power supply board of the Roland TR-808 (original 1984–86) as a KiCad rebuild, 220/240 V variant.

Contains Gerber (zip), 1:1 printout (A4) and schematic PDF. The layout is a copy of the historical design and was not designed against today's safety standards (see VERIFICATION.md). SW_A/SW_B are 3.75 mm apart. Not manufactured, not tested on a unit. Rev0.2 increases the mains-side spacing.
