C46 was leaky and replaced, no change.
I think the reason there was any output at all is due to the cathode current being drawn through the feedback circuit and the output transformer secondary and to HT via the screen grid.
The cathode resistor and decoupler do not go directly to ground, its an unusual circuit.
