Service Manuals

Service manuals and circuit diagrams for most popular CB's.

We can supply photocopies of service manuals or individual circuit diagrams for most CB's made from the 80's up to current models.

Unfortunately the quality of these varies greatly - some of the diagrams we are using are now over 20 years old!  We will provide the best copy that we can - on the basis that anything will be better than nothing!
