Tube tester recommendations

jtwrace, I felt the B&K 747 was a little underkill, good for quick checks but not the level of accuracy I was looking for so I bought a Hickok 539B it's beautiful but may be a little overkill!!! After playing around with a Hickok 725 I think it is the" happy compromise" between the two, no resetting for second section and more than accurate enough for most purposes, as a novice for a novice, I think it's a great choice.

An excellent choice: (http://cgi.ebay.com/Hickok-KS-15750-L1-Tube-tester-Western-Electric-co_W0QQitemZ280249394273QQcmdZViewItem?hash=item280249394273&_trksid=p3286.m14.l1308)

Samhar-

Thanks for the info. I will start the real search....

Jtwrace that should be 752!!!!

Update! I now have a Roger Kennedy digitally modded Hickok 539b. Pic in my system, click on Hickok then click on the picture to enlarge. The 539b has two power transformers. One to supply all the heater (Filament) current and the other to provide all the test measurement voltage/current. So the Tube Under Test (TUT) load is divided by the heater and test transformers also improving the accuracy of the tests, and reduces the load on the test circuit and its power transformer. They also have another advantage of having a separate AC line set volt meter. This helps by reducing the effects of the line sag (accuracy issue). In addition this models also has more than one test signal level allowing for more accurate test results on a wider range of tubes. The modded unit has a DC plate current mA meter making it a great tester for matching power tubes. One section at a time is checked and resetting is necessary for checking second section. In the picture I'm testing all the #1 sections then resetting and testing all the #2 sections.
