Elements of Radio Servicing by William Marcus and Alex Levy. c 1947, McGraw-Hill Book Company, Inc. This is a very comprehensive book on the repair of superheterodyne tube radios. Includes a stage-by-stage look at schematics, functions, troubleshooting, and typical problems. Focus is on troubleshooting with minimum test equipment, mainly soldering iron and signal generator. Sections on alignment. Written for servicemen, not engineers, so it is light on theory and math. I found it very readable, with a little concentration. I read it through before I ever tackled a restoration, and still refer to it often.

You can find it in 6 pdf files (a few chapters per file) on this page: http://www.antiqueradios.com/archive.shtml

You might be able to find used copies at used bookstores. That is where I got mine.
