I had that TV as a kid! Its early to mid 90s I remember playing Sonic 2 and Ristar on Xmas 1995. I never knew about RGB or about picture settings back then. It developed a problem with turning itself off after 5 minutes, so it got chucked away, If I knew as much as I did now maybe it would have been fixable.
I only ever used RF and composite, and it couldn't do 60hz composite, and the sound was mono.
Your best bet is a late 90s - early 00s era black cased trinitron before they started using scan velocity modulation and 100hz.
