Color CRT alternate question for 1969 Zenith

[bhegges]

I recently replaced a 25xp22 with a Zenith 23vcmp22 which I got from the ETF. Other than bending very slightly the 4 metal corner brackets to fit tight to the tube it installed just fine. I am intrigued about the bias question, my gray scale is rather blue, I figured it just needs further adjustment.

I also would like to find data sheets on these CRTs to help answer our questions.
