Gentlemen,
I have recently purchased a Hickok I-177 tube tester with its expansion box. As the expansion box needed an intense recabling, I am now undergoing the process of adding other European-type sockets not originally present on the board while I’m on the task.
My concern is of course the fact that most European tubes are not listed in the data sheets. I see that a lot of work on this matter has been done by Nolan Lee (that’s why I was willing to <a href="http://www.radiomuseum.org/forum/any_news_about.html">get in contact with him</a>) and other fellows here and there on the net, but many tubes are not yet covered. Just to name one type: tubes with side-contact base.
Since the set up of the ammeter on the I-177 is very easy (one potentiometer only, the other one is fixed once the scale is set to MicroMhos) I was wondering if some of you fellows developed a general method to test tubes when the tube chart is given. Tube charts are easy to find on internet, so they’re no longer a problem.
What about comparing set-up values with the TV-7 model, which seem to have more literature? Is there some kind of conversion procedure to set the I-177 once the setup for the TV-7 is given?
Any comment on this subject is welcome.
