I would back up that statement about checking on Roger at Alltubetesters. Let the Buyer beware... I currently own a Hickok / Western Electric KS15560 rebuilt by Paul Hart in Atlanta, he is an Electrical Engineer (retired) and does great work, he has a number of testers he can rebuild to sell ([email protected]). Also own a Hickok 752A (rebuilt by Paul) and Jackson 658. One thing about Paul is he can modify a tester, mine have been modified to run with a Variac which increases the accuracy on all tubes, especially high heater current tubes because there is no loss in the line adjustment pot. Mine can also can measure plate current. As daveyf above says, if you want to test at 600 volts you'll need a specialized, modern tester. Mucho $$$$. But the older Hickoks, if calibrated, do a fairly good job within their voltage limitations.
Tube tester...anyone own their own?
Since a lot of us utilize tube based gear, I am wondering how many of us own a tube tester? I am considering acquiring one, not sure if I would look for a Hickok or another brand/type.
if you are considering a tube tester, or already own one, do tell us your recommendations and your experience with the particular type you own.
