First off, i believe the extended warmup until things stabilize was either caused by one or two faulty connections from a large transformer mounted on the side of the chassis under the horizontal components. Now at a cold start, it is out of horizontal sync for 20 seconds or so after the picture appears on the screen.
Another conditions i just noticed is after following the horizontal sweep adjust procedure in SAMs for the series b through c, which should be similar are as follows.
First real adjustment is to adjust the horizontal drive maximum clockwise until there is not picture crowding. At maximum i don't see any crowding of the picture. Just a reflection line because of this next condition-The picture is wide, and will not shrink all the way down to where it should be even at the extent of the horizontal size adjustment coil.
What could cause this?
I still have a dark picture. I don't have a CRT tester so i couldn't test the picture tube.
I did adjust the ion trap magnet for the brightest picture. As found, It was preset as far back as it will go until stopped by the plug socket, and that seems to be the area where the picture is the brightest at the proper rotation. Not sure if i remember any other sets with it all the way back there.
