Also the 'top secret' tube I was planning to give a try has been debunked, for the reason below which was given to me be Jeremy. I think this info. is also useful to consider when experimenting with new tubes:
(The Ember's heat current) "Maximum output is 1A with a little overhead. At the very very best with modification we can do 1.5A"
If running dual tubes you must make sure each tube does not draw more than approx. 0.6A at the most, at risk of damaging the heater circuit.
That's a shame, but there will be others.
