Hi,

could I instead of trashing the tube to flip it to the left filament and continue to use the unused part of the cathode, plate and filament?


Sure you could.

Theoretically it might be the case but the entire tube now should be filed up with the residual gas of right triode operation and the getter should be greatly eaten.


We have several modes that may 'fail' a valve, excessive gas and no getter are one, no emission from the cathode is another.

So, if you have a "halve used" tube who still has decent getter, 'flip' it with impunity....
