Testing a GZ-37 tube


Can a GZ-37 tube be tested the same as a CV378? I have 4 (top rated) testers here and none of them has this tube listed! My TV-7D/U has the CV378 listed and I know these two tubes can be substituted in my amp

Thanks for that information Hifihvn. I tried it with my other testers and it worked well.
Now how about the PX25 tube? None of my testers has that one listed. Do you know of another setting that might work for it?
I did a quick check on the net and came up with CV1040, CV1064 and CV1343. I'm a bit hesitant to try any of those with a very expensive tube unless someone knows it is safe.
Thanks
