looking for a schmatic for a '72 GE color set

[drh4683]

Ive been working on this '72 GE 19" color set I picked up a few months back from the estates. I found a couple bad tubes and one of them is the video output tube. The shorted tube must have caused some other part to either short or open in the video circuit. I cannot get the brightness to cutoff. This is the most diabolical TV I've ever worked on. the designers of this chassis must have been inspired by a rats nest. According to my sams index, this set should be in folder #1231 from sometime in 1972. Any help is greatly appriciated.
Thanks
