The screen is only connected to HT directly if the screen voltage for the valve is the same as the HT voltage for the circuit. Otherwise there is a dropper resistor between the HT line and the screen which will drop sufficient volts as the screen current flows through it. If the valve is triode-strapped the screen is connected to the anode.
