What does "pentode in triode mode" mean

Posted by Alex on April 15, 2000 at 15:47:03:
As far I am concerned what matters is the singled ended circuit.
The "T" is not what matters to me as a conceptual matter, and furthermore I refuse to be a snob about 300B and 2A3. Having said that,
would someone please explain to me what "pentode in triode mode" means?! I've asked this question many times. Is it
1. really a SEP or
2. does one physically go into a pentode tube and "reconfigure" it?
I don't care much because I'm getting a "non-traditional" (sometimes described as bizarre) "T" but since I have thought of this (Zen amp)
and since you brought it up, I'll ask one more time what exactly does "pentode in triode mode" mean.
