The service manuals of old professional equipment are truly amazing, the schematics are shown in three different abstraction levels, every single connection is shown, waveforms at 100 different test points are drawn, every single component is listed, with step-by-step test and calibration guidelines. You can almost remove everything from the board and put it back together with a service manual.

Something that today's consumers can only dream of...
