I have 6AD6G indicator, which more often than not stays off, occasionally comes on, pretty dim in appearance, but when "on", operates normally and sensitive to the strong station.There is no loose connections.Shows 230 DC at the pin #5 (B+) instead of 180, but this 50v difference is across the board on all tubes- possibly from using 47 and 23uF caps instead of 40 and 20(?)
All other voltage readings are within norm.And I do not have the tube tester.
Time for the tube replacement? Thanks.
