got me a portacolor

[DaveWM]

green is somewhat weak, tested the CRT, yep green gun is weak...

[DaveWM]

screen shot. I did replace the 6AC10 seemed to help the color a bit

[DaveWM]

so is the 11SP22 compatible with a 10VADP22? I am assuming the 11 and 10v is the same, question is focus voltage etc...

Hi Dave:
This guide originally from Video Display Corp says "YES"

Do you have a spare 10VADP22, is that why you are asking?

I saw that same guide and thought is said no. I am looking to see what would work, do not have a spare. Seen some other threads since posting and seems like there are low volt and high volt focus, I assume this is a low volt, and also some mention of the anode cap on the other side.

I dont think the CRT is the real problem, the grid drive to the green gun is REAL low, like 5v PP vs the 28v ref in sams on a keyed rainbow generator. I plan to look into the parts in the matrix.

You are right on the CRT sub. I was, shall we say, a bit over optimistic in my interpretation. I was comparing subs as a group, not line-by-line.
