You paid $600 bucks for it, and you want to throw a TV in it?
And one that doesn't even have Component video, to boot?
Spend PART of the $168 bucks the TV costs, and pick up the ArcadeVGA.
That'll leave you some left over for the controls, PLUS it will let you put it all back in case you ever want to sell the cab.
I can't see spending that kind of money on a cab, and then spending MORE on top of that to make it work WORSE.
And those things had a MARQUEE on them.
I thought I went big, sizing mine at 10" High.
