In Reply to: Idea for Prolonging Tube Life posted by Lee of Omaha on September 1, 2011 at 08:37:05:
Tubes 'wear out' mostly due to decreasing
cathode emissions. Hydrogen does leak in, but
the cathode loss is the greater 'loss'.
Some cathode loss can be reduce by using a reverse
voltage plate to cathode, or with the control grid.
This rejuvenation process is temporary, the cathode
will become weak and have very low emissions.
Tube life can be prolonged by keeping the tube
cool. An added glass cover would cause too much heat
to build up in the tube elements.
