That's correct Geof. Each section of the DL94 heater is rated at 50mA. Looking at the schematic for the 'Henley' it shows both sections connected in parallel so the valve will be drawing 100mA. As you're probably aware, in some set's provision is made for the user to change between one or both filament sections of the output valve(s) with an 'economy' switch in order to prolong battery life. Not used in this set though apparently.
