The voltage across the 2.49K resistor on the center C4S board above the 12AU7.  It should be well under 5V on both sides.
Did another check. The b side 59V value was actually due to remaining 6AQ5 tube being loose on one side so it is 54V. What should I check since the values are way off 5V?

I would suspect that the ground wire (or jumper) feeding that portion of the board is broken.
