Title: Tube Tester Post by roggae on 05/23/17 at 03:42:12 So with all of this tube rolling, it's come to my attention that perhaps i could use a good tube tester.  Where does one buy such a thing? I see them now and again on CL and the like but often they are damaged or too "vintage".  Anyway i'd love to know where i could pick one up and what to look for and what to avoid.

These old testers aren't usually calibrated and have quirks that make them hard to use. The people who know how to work on the units are disappearing fast. I have mi Hickok 6000 out at Roger Kennedy's going on 4 years now and I can't seem too get it back from him. So think hard about the whole proposition.

Title: Re: Tube Tester Post by Lonely Raven on 05/30/17 at 23:51:37 I agree - the vintage testers are usually fine for looking for bad faults, but don't usually run at actual amplifier voltages.  Sure they can test for shorts and breaks, but they don't tell you if the tube is noisy, and the readings could be accurate to +/- 25%, *and* as mentioned are only at the tube testers voltages. If you were serious about tube testing you'd look into something modern, but you're going to pay for it! http://www.maximatcher.com/ http://amplitrex.com/ If you're set on adding something vintage, which is still pretty cool and does have some use (I have two from the 70s), here is some reading for you. http://www.alltubetesters.com/articles/tester_guide.htm
