Hey John and Mark
I hate to bug ya, but I'm a little confused again!
One lead to my Brightness control is going nowhere
According to the schematic, one end goes to B++ and the other to the Contrast control.
I don't think that's correct though. That end of my Contrast control is going to ground (pin 6 on the 6SL7GT Vert Sweep Output) and it looks original. From what I can make out from Mark's 7VT5 pictures, his Brightness control is going somewhere around the ballast tube. Maybe to ground as well ?
I think that schematic might be missing a dot where the vertical line intersects the "ground" horizontal line. (see attachment)
I'm also wondering if that wire from the Video Amp to the Contrast control should be shielded. Isn't that what the dotted line around it means? My lead is just plain old wire.
Any ideas? Thanks!
