Thanks to all those who have contributed so far by sending in service manuals and vintage valve radio circuit diagrams. If you have any manuals, schematics or circuit diagrams you’d like to share, please email them to me. Some of the radio manuals listed are only circuit diagrams. However, the schematics can often be enough to help in fault finding. Full service data on vintage valve radios and some transistor radios and record players has been included where possible. To make things easier, I’ve listed the manufacturers in alphabetical order.
