CRT televisions are all about the art of compramise. They are not like todays' digital sets. Do not beat your self up trying to get perfection. All any of us can do is get it as close as we can and leave it alone. All the best,Tom.J

Truer words...


It is really easy to go off and fight windmills that are baked into the design when you want to optimize a tube set...Knowing when to declare good enough, or balance between two incurable issues that can not be fixed together is important to staying sane.

I gotta concur with the last two postings. Any B&W tube TV, especially a low B+, minimalist design, is gonna have very fluid parameters in its performance, like tubes and components aging, low and/or fluctuating line voltage etc. The design has built-in 'headroom' to allow for this. And very few sets if any will display perfect linearity, either horiz or vertically. Even If you set everything as near 'perfect' as possible, it's gonna change on its own.

The results you've already attained with this project have knocked everybody's socks off, and achieved performance beyond any typical BW set of the period.

(Edit) There's an old adage relating to model aircraft design, but it applies here as well: "Perfectionism is the manic form of fuddyduddy-ism."

I would be 110% happy with what you have there now.
