You can get the recommended output transformer impedance from the 35L6 data sheet. At 110 VDC plate voltage typical of an AC/DC set, the recommended transformer primary impedance (load resistance) is 2500 ohms.
And yes, even with no plate voltage, the screen grid will still draw current, which is why you are still seeing current in the cathode circuit.
