REPLY:

Perhaps he is, but he should say so. The entire article is about grounded grid
amplifiers, not the characteristics of a tube disconnected from all circuitry.

The paragraph where the infamous quote appears specifically mentions the Super
Cathode amplifier circuit.  Why would anyone assume he is talking about a tube
NOT connected into that circuit?

Clarity in technical writing can be elusive, as we can all see.  :-)
