     The GALAXY SERVICE MANUAL
                             Second Edition 

Here's the latest edition of our real service manual for these popular CB radios and Ham radios! No more fuzzy photocopies of schematics that you can’t read no matter how large. No more guessing about all the other essential technical information you must have, like voltage measurements, PLL and circuit theory, block diagrams, ‘scope photos, alignment procedures, and much more.

Similar to our Uniden Export Service Manual, this expanded new 32-page book was completely written and illustrated by Lou Franklin in his famous crystal-clear style. The schematics are all redrawn for greater clarity in 11" x 17" sizes, with active stages and trimmer adjustments plainly labelled, and part numbers converted to the American style (".047µF" instead of "473M", etc.).

Most of the models listed on this page were made by Ranger Communications Inc. (RCI) and based on the original Uniden PB010 export chassis described in our Uniden Export Service Manual. Those that weren't are Chinese or European copies using identical circuits and often the same parts numbers. Study this one book and you'll understand all of them!
