New CRT working!
I put the 20CP4 in the Wilcox-Gay set tonight, it had a 21" tube in it from 1977, it was the wrong tube and it didn't fit the mask right and the chassis wouldn't slide in enough to get the knobs on, also it was an Electrostatically focused tube where the 20CP4 is Electromagnetically focused, this fixed all those problems.
I was a little surprised that this Aluminized tube needed an Ion trap but it does, no biggie.
It looks great, all the labels are missing on the back so I don't know which adjustment is the focus, it needs touching up but looks pretty good for right out of the box!
