Hi

I'm not sure if the Radiotron Designer's Handbook will give you what you are looking for, or not. It's been a while since I looked at my copy.

Some of the radio books written in the 1920s and 1930s go into detail about the construction of vacuum tubes. I'm thinking about Modern Radio Servicing by Ghirardi, which goes into detail on the fundamental circuits used in radios, and then gives tips on how to service them. Not a small book, quite comprehensive.

Alan Douglas can probably suggest more books, or more appropriate books, on this subject.
