If resistor 57 is too high then the plate voltages for the 3 tubes you list as low would have low voltages. The two audio tubes would have normal plate voltages like you show. Resistor 57 should be 9k ohms, no higher than 10k by my standards.

BTW 6K6 should have 265v on the plate, so your reading is normal.
