In the Thread: Get, or made up a tube tester, it’s necessary
Post Subject: More toys for the well heeled tube-o-holic:Posted by Paul S on: 1/23/2007
Little I know about tube testing.

Here is a link to one that can do a test series on tubes at rated voltages, including 6C33 (with extra-cost adaptor, of course), and it will compare sections at once:  http://www.amplitrex.com/index.html

Successfully screen only 1,000 tubes you can actually use out of your wholesale lots and it pays for itself!

Not mentioned yet (at least not in a way that allows me to  recognize the information): How are people testing, determining and matching tubes and tube halves for gain, apart from running the math on an "amplication factor"?

And please pardon the simple questions, but

If all I can do with the usual tube tester is check largely irrelevant data, and if the usual sellers take back the duds they already screened with their irrelevant tests performed with the usual tube testers, then what, really, is gained by further testing?

Best regards,
Paul S
