Description

Knight Model 600 Tube Checker / Tester. W/ Roll Chart
Condition is "Used - Good".
Includes PDF manual if desired(e-mailed)
This tube checker was tested with three Silvertone tubes from a Sears and Roebuck 1481 guitar amp. All three tubes were tested for short and emission. I was able to do a gas test on two of the tubes as well as multiple section tests on two of the tubes. The tubes tested were a 6X4, a 6V6 GT, and a 12AX7, and all tests checked out good. I did not have any bad tubes to test.
I can e-mail a PDF manual that I found for free online for the unit to the buyer if desired. I am not sure if it is the entire manual but it seems to have all the necessary information.
Overall the tube checker seems to be in very good condition for its age and the roll chart rolls very smoothly. (*Updated- Added one picture that shows two small places I glued to repair the covering where a couple of small tears had happened.)  It was lightly used as it came from the house my father grew up in and they mostly used it for their television set rather than having to call the TV repairman so often.
Pictures show condition as well as function and checking of a Silvertone 6V6 GT tube for short (short light is meant to be lit with switch 7 up on this tube according to the manual and chart), emission, and gas tests. If you have any questions feel free to ask and I will do my best to answer.
