Hello all,
Sorry for the delay in responding, but I grew very frustrated at my inability to solve the problems with this set, and had to walk away for a while. I wish I had half the ability of many on this site. Well anyway, I'm back at it. I've taken pictures of signals at various points, and need your help in determining where to go from here. You'll find pictures of the signals I'm referring to in the link that follows. The brightness and contrast are working, but most of the time I don't have horizontal or vertical lock. I hope you're able to help me out of this rut.

Photo #1: Video signal to first video amp. Scope is on the 2 volt scale.
Photo #2: Output of first video amp. Scope is on 2 volt scale, probe at X10.
Photo #3: Input to kinescope. Junction of C141, R148, and green lead to kinescope. Scope is on 5 volt scale.
Photo #4: Cathode of D-C Restorer. Scope is on 5 volt scale.
Photo #5: Plate of D-C Restorer. Pin 2 of V114-B. Scope on 5 volt scale.
