I missed a broken ground connection on the main board that took a while to track down. My quick fix was to solder a wire directly to a tube pin. Later when I pulled the board I did a proper repair.

I did take it all apart and washed it down with Simple Green. The results were impressive.

I also swapped out the yoke as the wiring was cut, spliced and deteriorated.
