PRECISE 111 111A 111M Tube Tester, Choose Manual or Tube Data or Both, BIG BOOKS

Description

Here are GIANT compilations of info for the Precise 111 series of Gm / Em tube testers.  These testers are the creme-de-la creme of tube testers.  Some of this info about these testers is available for download on the internet.  I cleaned up and organized all the
relevant
info, and offer it as very nice comb-bound books.  Choose the book you want.  Avalable are:
Tube testing data charts with testing instructions including 1954, 1956, 1959, and newer.
Manual set with Owners, Assembly, Calibration, Schematic, and Modification info.
Both books in one One GIANT compendium.
All books include oversize clear front and heavy back covers.  Manual Set includes 11x17 schematic foldout for 111.  Tube charts work with 111M, but Manual Set does not include any info on the 111M.
Please note: Pages 7 and 8 are missing from the "Precise 111A Modification Kit" manual section.
These are good copies and easy to read.  Being a copy of a vintage manual, it may have small marks and imperfections.
Pictures show what each specific manual looks like.  Note: Section separator pages, binding spines, and back cover could be other colors.
