ETF - Television Schematic Diagrams

Television Technical Data

We now have high resolution service information and schematic diagrams for many pre-1945 and postwar American sets posted here. Note: these are very large files. High speed connection suggested. Unless otherwise noted, these documents were scanned by Tom Albrecht. If you have a set you'd like the Sams or Riders scanned for, Tom has agreed to do it, as long as the material is in the public domain (generally pre- 1964 sets). Email your request to the museum, and we will forward it to Tom.

The technical manuals published here are in the public domain. If you need information on newer (post-1964) sets, please contact Sams Technical Publishing.
