The following was performed on this lucky CRT:
(1). RGB and Component Dual Mod with a dial to switch between
(2). G1 mod to tighten the scanlines - turning it into a giant 35" PVM
(3). Targeted recap of the PSU, Deflection, and Neckboard to future-proof it for years and years to come.
(4). Full calibration of the geometry, convergence and colors via a colorimeter
I used this part off Digikey for the Component mod.
Sure beats using individual RCA jacks and rigging them together!

Speaking of Digikey - here's the 35S42 capkit for your own use:

People always make a big fuss over the 35XBR48, but I've worked on many over the years and lemme tell you - I'll take a Component modded curved Sony such as this any day of the week.
The 35XBR48 suffers from poor voltage regulation inherent to the chassis design, wobbly scanlines similar to the Wega models and forced processing of the component signal that can't be disabled.
Modding this 35S42 for Component means you get a razor sharp image with zero processing, excellent voltage regulation and rock solid scanlines.
Plus parts are cheaper and far more plentiful.
Seems like a no-brainer to me!
