RE: Maybe that third one is just for show?

"If the heater is covered by the plate and or cathode structure then it can seem to be not working even though it is working"
It is not just the heater that glows. In a normal indirectly heated tube the heater gets the cathode so hot that the cathode also glows.You will not see this if the cathode is covered by the plate but in the 6n1p (and the 6080) the cathode is not covered by the plate. The tube below has holes in the plate and you can see the cathode glowing.
