It goes deeper than that, Tom. We have way different educations.

Nothing but heavy grid current or divine intervention can make a medium
Mu triode draw much anode current. As I recall, we went through this
milarkey before when you were claiming that the 3CX3000A7 high-mu triode
could be operated as a grid driven linear. In truth it can. P out is c.
100w.
When are we going to discuss the 8877 that failed from gold sputtering in
an AL-1500 amplifier? When are you going to explain in detail why the
8877 supposedly needs no suppressor?
you are one piece of work, Mr. Rauch.
