? As I understand it, Ian, the person who is in charge of the rewrite
project is the same "expert" (p.72, Sept, 1994, *QST*) who wrote:
"Measures' inference that modern tubes used in linear amplifiers have
inherent "VHF parasitic oscillations" is incorrect. Parasitic
oscillations are a result of improper amplifier circuit design and/or
component layout."
- - Does this sound a bit like Not Invented Here Syndrome?. . Are
tubes with substantially more VHF amplification, less capable of VHF
oscillation?

? Indeed, Ian, indeed. It seems a tad odd that the guy who is in
charge of an engineering book rewrite, works for the Marketing Dept.
instead of the Engineering Dept.

? Apparently, the thinking has already been done.
