MFJ-407B Deluxe Electronic Keyer Owners Manual With Schematic OEM

Three pages including schematic, owners manual.

This is an original MFJ manual/document.  When assembly began to shut down at MFJ, I bought the entire stockpile of printed manuals and printed instruction sheets.  Most of these are pristine.  Every now and then one might have a yellowed edge, but that is unusual.  

Ships quickly and safely from Mississippi.
