I am trying to understand the purpose of this tester.It is recapped and calibrated and it works, but in some strange way. For example, I have 2 globe 47s, which are very weak, I bought them as such. Using the tester, one shows 70%, another 80%. So, I am elated for a moment.Putting each of them to one of my sets- the volume as well as reception drops 50%. Any ideas?
Realizing it is a cheap tester, one should expect better than that.Thanks.
