This new version is 288 pages of text, 102 more pages than the original version had. Also included is a data CD of important information, one section covers deciphering tube date codes, most of which has not been available until now.
The new version of the book covers about 13,000 ( ! ! ) tube types, plus another 4800 or so radar / microwave parts on the data CD. Also on the disk is info on very strange and unusual tube types, another 106 pages.
The project reflects 20-plus-years years of corporate files (RCA, Eimac) coming out of the woodwork, the release of about 40 years of RMA/EIA tube registrations, plus 19 years of work by the Tube Collector’s Association’s authors.
