Some things to try:

Bridge the 100 mfd cathode bypass.
Rotate v lin while measuring cathode, pin 9. It should go to 0 at extreme end
Bridge electrolytic on the 275 volt source
Recheck cap values that were replaced. C 40 will have most effect on height.
Height and lin pots and the .0015 (C43) were common failure points.
The small pix accounts for the low neg voltage on pin 7 since the source is the output plate.
Make sure pin 7 measures 68 k to ground.
