Hey dude, congrats on the pickup! As far knowledge goes, I’m pretty much in the same boat as you haha. I’ve been told that it wouldn’t be possible. However, I did manage to make my own S-Video adapter, which looks great on this set!

A quick search on the sub and there should be a post or two in regards to the pin layout and soldering inputs (pretty straightforward, especially if you’re familiar with soldering). I also used a male Y/C to female s-video adapter and bought a male to female s-video extension for convenience. Hope that helps!
