EICO 667 Tube Tester Manual w/ Charts & Updates, Choose Roll or No Roll Style

Description

This is a bound and printed copy of the EICO 667 manual with tube charts.  Choose your style of 667 tube checker: With Roll Chart (older style) or Without Roll Chart (newer style).  There are some slight differences in the the instruction manual and schematics for the two types of testers.  Both tester types include the same three tube test data charts: 7712 (most recent), 7315, and supplement 667-05.  Reprints are from vintage books and are not perfect but are readily legible.
You can also choose Both Roll and No Roll.  This gives you the instruction manuals and schematics for both types of EICO 667 Tube Testers.  The 3 test data charts are identical for both tester types, so they are not duplicated.
Please let me know if you have any questions.
