RCA WT-100a Tube tester
Just acquired this awesome tester. Built in 1956 this tester is a laboratory grade tube tester and has test accuracies of within 1%! This tester was used for research and development of tubes and was used at the RCA plant in New Jersey. You have to actually set each pin up individually to the right position so you would need a datasheet for whichever tube you are testing. It also applies up to 300 volts on the plate and screen grid! Does anyone else here have one of these and know how to use it?
