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

Description

This is a comb-bound, printed copy of the EICO 667 manual with tube charts.  Choose one of the following three books:
EICO 667 tube tester with built-in Roll Chart (older style)
EICO 667 tube tester without Roll Chart (newer style)
Both manuals in one book
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 (1977 is most recent)
7315 (1973)
Supplement 667-05
Reprints are from vintage books and are not perfect but are readily legible.
Choosing "Both Roll and No Roll" 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.
This comb-bound book has an oversize clear front cover and an oversize heavy back cover for extra protection.
Please let me know if you have any questions.
