I missed one setting. I need to add the GM scale is set to C 6000 Micromhos.
Need help with Tube Test TV-3B/U
I am trying to test a 6922 tube. I looked up 6922 on the chart. It has the following setting
6922 6.3 EV7-6080 30 --- C P3 2500 Triode # 1 3200-124
6922 6.3 EV2-1030 30 --- C P3 2500 Triode # 2 3200-124
I set the following
Filament voltage 6.3
Filament E
Filament V
Grid 1
Plate 0
Screen 3
Cathode 8
Bias 30
Function tube test
Everything else was left alone. I turned on the unit and inserted tube 6922.
I pressed P1 (line adj) and adjusted meter to line test. When I press P3 the meter does not move. I think this is my problem. Maybe need to set something else?
Does anybody have the same tester and can run through my steps and figure out what is I am doing wrong? Also how do I test for a short? I know my tube is good.
