That's a very interesting addition to the data sheets I have accessed so far. The general consensus seems to be: output power = 3.5 W with an anode dissipation of 5 W, which gives a total input power of 8.5 W. At 370 V, this power represents an anode current of 23 mA.
The suggestion of Restoration73 to wire a 5.6k resistor in the HT feed represents a voltage drop of 56V for every 10mA of anode current - a useful option. The alternative is to add some droppers to the PSU (as suggested by G3RZP elsewhere] to bring the HT down to somewhere between 300 and 350V for the whole set. Time to dig out some large WW resistors.
Many thanks to all
