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.
