What is the condition of the HV rectifier tube--AND..is it getting proper filament voltage ? because if it is weak or not getting proper filament drive...you WILL get low HV.

I agree with this here.... Also, when the 'Scene' changes and the HV goes down
does the picture width come in, or remain full....? Even a little....? If no, then
I'm even more inclined to think about the hv rect.

Also, I have never checked this but I would assume that a weak tube would
be conducting less current, so.... less cathode current right....? Basic....
So how could a tube conducting less current be dragging down HV....? It should
not.... I imagine when this is fixed, the picture should be a good bit brighter...

And in the videos the scanning lines are nice and defined... Not really a bad
tube looking..... right...?

Also, Sams usually has brightness settings, specified for their measurements...
you should probably look at them.... follow them....

Also, if recapping and on each part you "round" values up, down, or sideways....
after a few parts yer gunna have an entire tv with parts 20% off.... not good....

Be careful how you chose to determine filament voltage on the HV rect. You might
just wanna get a new one off ebay...
