Notes:
- All resistors are 1%.
- RGB termination / voltage divider resistors values are depending on monitor jungle (chroma/deflection) IC.
For jungle ICs with 0.7Vpp RGB inputs (like TDA8366):
R1, R2, R3: 0 Ohm,
R6, R7, R8: 75 Ohm.
For jungle ICs with 0.5Vpp RGB inputs (like TA1276AN):
R1, R2, R3: 30 Ohm,
R6, R7, R8: 75 Ohm.
Attenuation / divider resistors R1, R2, R3 can be changed to 24 Ohm, and termination resistors R6, R7, R8 to 51 Ohm for "proper" 75 Ohm termination. - Blanking voltage divider / pulldown resistors values are depends on jungle IC requirements.
For 3V inputs use R9=1K/1.2K, R10=2.3K/2.8K, and so on.
Some ICs require pulldown R10=10~50K.
R12 can be omitted but R9=120R~180R is recommended to limit current. - More info on Blanking voltage divider: sector.sunthar.com/guides/crt-rgb-mod

Questions
How big is the RGB SCART VGA Breakout PCB?
It measures 81 × 40.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RGB SCART VGA Breakout use?
25 parts, built around the BAT54W and SJ1-3535NG. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the RGB SCART VGA Breakout KiCad files?
From the proboterror/RGB_SCART_VGA_Breakout repository on GitHub, at the commit this page was made from: the board is KiCad/RGB_SCART_VGA_Breakout.kicad_pcb and its schematic KiCad/RGB_SCART_VGA_Breakout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RGB SCART VGA Breakout design in my own project?
Its repository states no licence, so its author keeps all rights: ask proboterror before reusing the design.
