Hi,
I just got the meter and after pots and switches cleaning , replacing the cap and resoldering some joints it works fine (or may be it is just my wishful thinking). Fact is,I have a bunch of old tubes and for some reason they all show "good" between 80 and 90.Isn't it too good to be true? I follow all instruction and set the "U"and "D" switches correctly according to the chart as well as the load setting.
Also at the same time every tube shows "short" which they are not as I tried to put them in one of my working radios and they operate normally.Any ideas?
Thanks.
