Super Star 4900B Service Manual
This is a on going project to document the Superstar 4900B. I started working on this manual Dec 2000. You can display
and print it but publication on the web and commercial use are not allowed.
If you have test equipment and a 4900B or can help in technical writing and/or research and would like to help on this
project go to the CBTricks Message Board and look for the Superstar documentation Discussion Group.
Rev. History
Rev. # 1.0
(a) Put up on the site
Rev. # 1.1
(a) Worked on the Alignment hook-up diagrams.
(b) Put the parts lists with the board layouts
(c) Made a change to alignment layout
(d) Put a picture of the radio on first page.
(e) Schematic of the ASC PCB.
Rev. #1.2
(a) Schematic of MIC PCB
(b) Board Layouts MIC PCB
(c) AMC Mod Information
Next I need to work on the following sections.
Alignment Procedure
Export Frequency Modification
Parts List
Circuit descriptions
Semiconductor Information
Index page and index all the pages
