53 Sylvania up & running

[Mick AV-8]

Okay...hope everyone is having a good weekend. Trying to get in a few tweeks on the tv..without my wife looking for me..
Went through the horizontal circuit adjustments.
I did get the horizontal drive control to crowed in the center..and then turned it cc to remove crowding.
Also notice that the brightness contol knob outside the volume control on the front..does adjust the brightness..but it also enlarges the picture to eliminate the black band on the right. But the picture quality and brightness are to suffer and it is too bright..so I bring it back and there is a slightest of 1/8" band there.
Also as I continued on ..I switched the horiz. size switch to find the best picture size..and when I turn thr B3 horiz. linearity screw..that is suppose to make the picture symetrical from left to right..it does not seem to do anything at all. I mean I turned it way in and way out with no effect..good or bad.

Still a decent picture...some ghosting still present now and then.

So..Do you guys have the 1/8' black band there on the right depending on what DVD you are watching?
And do you guys sometimes have this ghosting effect now and then?
thinking...
Maybe I should just enjoy the success I have found up til now with all of your help!
