[R-390] A little OT: Military vacuum tube designations

[Dan Merz]

Hi,  Tube Lore is excellent and has the VT numbers. I really like the GE tube manual Essential Characteristics, as it has a table of industrial, military and special purpose tubes (4 digit numbers) and their corresponding tube types. I have the 1973 edition,  orange cover, which i think AES sold at one time. The version I found as a pdf download was not as complete with regard to the mentioned table. But I didn' t explore to see if the 1973 version was available. Dan
