CTI Tube Tester Manual + Data Charts, Choose TC-10 or TC-20, Commercial Trades

Description

This is a bound printed documentations set for the Commercial Trades Institute emission tube tester. Choose either the TC-10 or TC-20 manual set to match your tester.  This documentation set will help you assemble, maintain, repair and use your CTI TC tube tester.
Included are the following:
New copy of the Final Wiring Manual (Assignment 8)
Schematic
Answers to review questions for Assignment 8
Three test data tube charts
These charts include some antique 4, 5, 6 & 7 pin tubes that the CTI TC can test with the use of an adapter.
Original and as-built variation schematics are included if applicable to the model.  This manual is nicely bound with oversize clear plastic and hard back covers.
PLEASE NOTE:
As you can see in the pictures, the type font is pretty small.  The smallest lettering are some notes in the chart that are about a 5 point font.  Much of the data charts are in 6 point font.  This is because the original was reduced to 8.5" x 11" from 8.5" x 14".  My eyesight is terrible but I have a great optometrist.  I don't have any trouble reading these charts with my glasses on.  If you can't read small font without reading glasses, you will need to wear your glasses to use this book
Please let me know if you have any questions.
