Heathkit Tube Tester Manual Set, Choose TC-1, TC-2, or TC-3. Complete w/ Charts

Description

This is a bound, printed documentation set for the Heathkit Tube Checker.  Choose your model, TC-1, TC-2, or TC-3. This is everything you would need to assemble, maintain, repair and use your Heathkit TC tube tester.
Included is a new copy of the Assembly Manual (with schematic) and a number of the most essential
test charts and supplements.  Special effort was put into collecting the most important, and most recent test chart updates.
These copies are from vintage originals.  They are readily legible, but in some of the tube charts it's difficult to make out the plain font from the bold font.  The bold/plain fonts are used for the "short" test.  To overcome this problem, I'm also including charts for the CTI TC-20.  This chart uses the same settings, but also includes compactron tubes that you won't be able to test with these Heathkit testers.
TC-1 Missing figure for Step 3 of the assembly procedure.
TC-2 Includes a specs summary sheet
TC-3 Includes a supplement to test the new subminiature tubes.
Please let me know if you have any questions. Thanks
