Public Address (PA), amplifier, and tube audio schematics and diagrams for the manufacturers and brands listed below are published service data from vintage sources*. Each schematic is individually digitized in high resolution to provide the clearest possible scan in a downloadable, printable, Adobe PDF file. Most of these early tube PA and amplifier schematics are usually 1 to 4 pages of information.

Lists of tube PA amplifier schematics I have available for the vintage Public Address systems below will continue to be added through 2011.
