Thanks for that, Martin, This graph is really helpful, and is extracted from the Burroughs data:
This is for a different tube, but it does suggest that a current of around 8mA (which is what I am getting) with 170V across the tube is not entirely unexpected. I will report back when a few new supplies I ordered (which can deliver a higher current) have arrived, and I can then include an appropriate anode resistor. It looks like I will have to figure out the anode resistor value experimentally, because at these currents there is no such thing as a 'Vsustain' voltage to make it simple to calculate the anode resistor value, because in pulse mode, the graph suggests that the current in this operating range increases linearly with voltage, and the inverse resistance behaviour doesnt occur here....
