Default Re: Could that picture tube be OK?

Valvo = Philips
Mullard = Philips

Regardless of the brand on the label, they were sourced from the factory or factories that had the production capacity to make them at that moment in time. Small print indicates where a tube was made, just as with radio valves.

The high voltage unit might have also been made by Philips.

I would guess there are some deflection problems, likely related to paper capacitors being electrically leaky or short circuit and electrolytic capacitors being dried out or worn.
