This is a bound printed documentations set for the Commercial Trades Institute TC-20 emission tube tester. This is everything you would need to assemble, maintain, repair and use your TC-20 tube tester.Included are the following:

• New copy of the complete TC-20 Assembly Manual (Assignment 8)
• Schematic
• Answers to review questions for Assignment 8
• Two test data tube charts
  

Most of the TC-20s I\'ve seen are not built exactly like the schematic, so both original and as-built schematics are included. This manual is nicely bound with oversize clear plastic and hard back covers.If you haven\'t gotten around to putting together your TC-20 and lost your instructions, or if you have a TC-20 but don\'t know how to use it or fix it, this is what you need. :)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\". I have a great optometrist and don\'t have any trouble reading these charts, but if you can\'t read small font, this book is not for you. Please contact me about larger, but unbound options. 8.5 x 14 will cost the same but will be stapled only with no covers. 11x17 will be stapled, folded, have no covers and will cost more.Please let me know if you have any questions.
