Default Tube PS using 6H30 into a 6550

I was looking at a friends AR Ref 3 linestage. The PS is based on an opamp into pins 3 and 8 on a 6H30. The output from the 6H30 are pins 1 and 6 into pin 5 on the 6550. This seems somewhat backwards to me. What am I missing? How much voltage is needed on pins 3 and 8 on the 6H30?
