Riders - Gernsback - Bietman
Old Schematics Data 1915 to about 1950

Please read carefully, it will help you to search and to order your schematic diagrams

The Riders series was the most complete collection of radio schematics for the radio serviceman.  John F. Rider produced 23 volumes of schematics covering about 120,000 radios with 45,000 different schematic diagrams.  Many people have radios that are not in his compilation.  In fact, in the very early days of radio, many were built from purchased parts on kitchen tables, garages, basements, etc.  If the person doing the building was successful and had good merchandising skills, then perhaps his company became one of the names below.  This list was extracted from our CD-ROM and DVD series and if you have a radio that matches one of these names, we most probably have the schematic.  Take a look at the list below and at the bottom of the page, we will give you a way to order a schematic diagram.  if you do not find the one you have, don't give up, because we can probably find a schematic using a search. If your radio is not in this list of manufacturer's names, we can do a SEARCH SCHEMATIC.  Tell us what the tube numbers and how many of each type and we can find a suitable schematic based on the tubes in your radio.

Riders CD-Database series (6 CD's) - available for $ 299

Riders DVD (all 23 volumes on a single DVD) - $ 199

Riders Search Schematic - $ 18.00
