In Reply to: Tube life over bias rule of thumb? posted by used-hifi on November 9, 2016 at 16:50:24:
The RCA receiving tube manual is a great place to start-
As you over bias the tube you will cause the plate to off-gas and add to the shortening of the tube's life- in addition to the 'wear' that occurs from running the tube hot-
There may not be a real study for tube life at 110% bias, 125% bias, 200% ...etc.
And I suspect that the degradation of tube life is a bit more asymptotic than linear...
Why do you want to run the tube hot?
Happy Listening
