Default Re: CRT is brighter to one side

Hi,
This would seem a pretty good candidate to me- being Japanese it will probably be more reliable than something British from the same era! I can't tell whether it's a delta tube or a more modern PIL type. The convergence looks spot on to me so it's probably a PIL tube.
The shading, although it's not too obvious from the pictures, is a fault and not an adjustment issue.
The supply to the tube's first anodes will be derived from the line output stage and will have a smoothing electrolytic capacitor. If this has failed it could give this symptom.
It could be a number of other things but should be perfectly fixable. Between the lot of us we should be able to point you in the right direction.
I would say if it's nearby and a sensible price it's probably worth getting, but only you can decide if it's worth a gamble!

Good luck
Nick

Dangerman- you can obviously type faster than me! We are obviously thinking along the same lines though!
