[Amps] Care and Feeding of Power Grid Tubes, 5th Edition now

[John T. M. Lyles]

The 5th Edition of this venerable work has been released, dated Aug 
2003; I just got mine from CPI/Eimac, hand delivered by the marketing 
manager and VP engineering today on their visit today.
It is more comprehensive having explanations with bigger tubes, up to 
IOTs and multiphase cooled tetrodes with pyrolytic graphite grids. 
Looks like a lot of work went into this, and it well may be the last 
'bible' of power grid tube techniques to be printed.
