An excellent video as usual Trevor. Your success leads me to thinking about trying that front end myself, at my usual higher voltages. I may try a single loop on a rod aerial I have already and see how it goes.
It would be interesting to hear your results if you tried that Amie. These valves do apparently work more on beam principles so there may be issues with de-focussed beams but there is nothing better than trial and error
