Listed by Radiocity360 is a Knight Model 600B emissions tube tester with builder manual and tube settings chart along with settings updates and two socket adapters. This tester is in very good condition and was tested with a 6SN7GT/VT231 double triode and a 5Y3GT full wave rectifier tube, both tested with a Hickok TV7 calibrated tube tester to evaluate the performance of the Knight tester. In the photos each plate of the 6SN7 shows good test, the 5Y3 has a plate lagging a bit indicating that a resistor(s) may be out of tolerance. The shorts test worked well so overall this is a very good clean tester. All the dials turn freely and the roll chart is clear and not worn. The tester has good paperwork, clean and not torn or worn. The builder manual is complete. See below for a breakdown of what I checked. I did my best to be accurate so ask questions please.
