Mutual Conductance/ Micromhos, 9250

Where are you setting the English for the Mutual Conductance/ Micromhos test? The red dot near 92? Then use/read the 15000 scale?

Thank your for your reply Jea48. I did set the tester as you mentioned. I still get about 7000 reading on new tubes (should be around 9250).

Cygnus_859,

Are the new tubes you are testing actually labeled 6DJ8 tubes or are they labeled 6922 tubes?

6922 ( Hickok 600A tube settings and Mutual Conductance readings.)
6.3 EV-7608-0 27 90 P4 6500 Triode #1. R
6.3 EV-2103-0 27 90 P4 6500 Triode #2.
Mutual Conductance/ Micromhos 6500.

What you are reading sounds more like a new 6922 tube.

Cygnus_859,

How about an update.

I found it is hard to get repeatable readings for 6dj8 tube. When I use 15000 scale, the reading is too sensitive to English position. Every step represent about 500 on the reading. I don't know if I have a bad English.
I am still confusing about 6922 vs 6dj8. I can get over 10000 reading for some 6922 tube.
