I don't understand. If it's a delta gun tube how is it anything like the trinitron? Is it the shadow mask or lack thereof? Aperture grille?

I just meant the one I saw had a bright, sharp, clear picture without HV regulation/blooming or edge enhancement/ringing problems. Trinitrons are my standard of high quality for TV sets of that era.

Oh okay. I agree, too....even the late model Sonys with the failure prone chassis' usually looked good in terms of stiff HV regulation in a hi-contrast picture....and the old ones are phenomenal all around

The delta gun used in the quintrix tube is not standard.
Panasonic placed a flat grid between the first and second grids on that design.
It was a very short lived "dog" design, used less than a year, not many made.
