ManualMan specializes in amateur radio, audio, and radio-related manuals primarily from manufacturers who no longer support certain older equipment models or from manufacturers who no longer exist. ManualMan always recommends you check the availability of needed manuals from the original equipment manufacturer first. An original manual on a complex piece of electronic equipment (with multi-layer boards, path layouts, complex schematics, color layer identification, etc.) is always easier to read than a replication. If the manufacturer can no longer supply the information you need, ManualMan would be happy to serve you.
Bought my Flex-5000a Manual here, as I was uncomfortable with having only a pdf Manual.
The quality was excellent and the price very fair for what I bought.
