The good bad scale is accurate for color CRTs where a good portion of the emission is lost at the shadow mask before it can reach the phosphor.
If it is somehow dim with the chassis working right just throw a brighter on it.

This is, of course, very encouraging news. The cutoff definitely isn't all or nothing, it basically just does nothing, unless you ease off on the G1 voltage, in which case cutoff works more or less as it would with a stronger testing tube.
I'm okay with a reasonably dim picture, just so long as it doesn't blow out and lose focus whenever there's a bright scene, or text on the screen. I think that with the above info a basic recap is more or less justified, just to find out how well it works.
