Was thinking that these old high meg resistors might behave in a non linear fashion when current is passed through them. Voltage drop comparison during operation under load might reveal some odd behavior.

Pin 3 & 6 measurements with the 7N7 pulled might reveal socket problems if the voltage is still low with the tube pulled.

grasping at straws,
