>POWER VACUUM TUBES HANDBOOK, Second Edition - 1999, by Jerry
>Whitaker, CRC Press, ISBN 0-8493-1345-7.
>
>It's not cheap, but maybe you can find it second hand. 710 pages,
>lots of recycled material from his articles in Broadcast Engineering
>magazine and his other book, McGraw Hill's RADIO FREQUENCY
>TRANSMISSION SYSTEMS: DESIGN AND OPERATION. It does a pretty good
>'basic' job summarizing the basics of most gridded and linear beam
>tubes, crossed field and velocity modulation included. Covers water
>cooling, designing VHF cavity amplifiers, 'regular' tube amplifier
>circuits and classes, reliability concerns, microwave systems, and so
>forth. The organization is lacking foundation in some chapters but
>hey, there aren't too many new books about power tubes being
>published, with the demise of Care and Feeding. You still need the
>basics like Terman's Radio Engineering, SSB Principles, and Bill
>Orr's Handbooks. And I still re-read Herr Dittichs' out of print
>Tubes for RF Heating, from the Philips Company.

H. F. Dittrich is one of the rare authors who discusses
parasitic-oscillations. (Section
5.8, page 96, 'Parasitic Suppression Circuits')
