Is this a 7401 or 7500? Or something else? Screen is wavy, not crisp, and colors are nasty regardless of adjustments so I'm gonna do a cap kit and just needed to know what chassis it is. It's in a dedicated atomiswave sports shooting cab with 24" monitor. I can't tell due to the small vertical board on the right side of the picture with the 2 pots. None of the 7401 or 7500s I've seen had this.

Looks like a U2000 or U5000... I'm sure someone with mote knowledge will chime in soon!
 
my money is on 7401. STD Res chassis. 75xx would be medium and I dont think those games ran at medium (EGA) resolution.

That little board on the right is pincushion correction used on the chassis when its driving a 27" tube.
 
27" K7400 with the pincushion board installed. (And I've seen many of these installed on 25" tubes and working ok.)
 
Yup! It was a 7400. I read that thread that was posted above and got the number on the board which read WG2774G meaning 27" 7400. Thanks all!
