kevinmi Posted March 23, 2019 Share Posted March 23, 2019 I've purchased 2 tube testers in the last few years of of fleabay, and both have minor issues. My advice for what's it worth would to have any tester you purchase calibrated by a reputable service tech. 1 Quote Link to comment Share on other sites More sharing options...

seti Posted March 24, 2019 Share Posted March 24, 2019 I've been using a friends TV7 for a few years after using several others. It is my favorite so far. Quote Link to comment Share on other sites More sharing options...

tube fanatic Posted March 24, 2019 Share Posted March 24, 2019 The only way to truly test a tube is in the circuit in which it will be used. However, if you are only looking to sort out real duds, a simple emissions tester is all you need. The Knight 600 which Jim has for sale is a good example of that type.

I inherited a collection of great tubes vintage and modern. If you want to roll vintage tubes you should have a tube tester. If you start having issues and want to rule out tubes a tester it is quite handy. Not sure I could live without one. It is nice to know if the tubes you have been using are still in a good range... In the collection I inheritage was a box of about 30 6550a tungsols. After testing I was able to put them into matched pairs. There were 5 that were unusable.
