Along with these adjustments are switches to turn on and off each drive to the guns.
I have a Sony rack-mount monitor with the same feature (the pots and cutoff switches are in a little drawer) but it's pretty cool that they put the same feature into a consumer TV. Probably carried over from the CVM-3000...

I think Sony made 26" color CRTs before anyone else had made a color tube that large, but I think they started doing 27"s later, after the 30". The earliest Sony 27"s I've seen were late 80s, and there are both 26" and 27" Sonys listed in my 1986 J&R Music World catalog. If you count monochrome CRTs, DuMont beat everyone to the punch with their 30"!
