Tube tester recommendations

Whatever you decide to get make sure that it will test the tubes you use and was recently gone over or callibrated. Also make absolutely sure that the instruction manual comes with it. For me I use a BK DynaJet, one of the latest models before they stopped production. Easy to use, portable (as are most), and very accurate (also fully documented with all of the manuals).
Tube testers are an absolute necessity when buying tubes online as some choose to sell their old worn out tubes (using the test specs when the tubes were new) for high prices (I suppose they think that they only used the tubes for a few months) and you ending up paying full price for worn out or shorted tubes. (This happens occasionally - not the usual situation - but it only has to happen once before your out a few hundred dollars! So. . .either buy new production tubes from a reputable dealer, or get a good used tube tester (WITH INSTRUCTION/SERVICE MANUALS!) Happy Listening,

If you're looking seriously at tube testers,
here's a link to a "real" tester:

In any case, good luck with whatever you decide to get!

I own the Amplitrex tester. It is a terrific, idiot-proof machine that has MANY advantages over vintage testers: it does not have to be calibrated; its display provides step-by-step instructions on what to do; it provides results as real measurements instead of proprietary and arbitrary units; it also provides the standard tube operating parameters to compare with the test results; it provides a "subjective" analysis (good, weak, replace, etc.); it even allows a hook up to a computer to do actual tube tracings (i.e., it will test the tube under varying operating conditions and display the results). But, all of this may be overkill for most users, and it is a pricey machine.

It is hard to say what anyone really NEEDS, particularly if they are new to tubes. Even good information and accurate test results takes experience to utilize properly. Certain tubes can read "weak" and still have many years of very good life left in the particular application (e.g., a lot of small signal tubes, when run gently will sound terrific even when they test bad). A cheap tester that will uncover gross problems (dead tubes, shorted tubes) may be all one really needs. If you intend to buy and sell on line a lot, you may need a better tester.

When you say "just getting into tubes" what do you mean? Also, where do you want to go? Do you want to roll tubes? Do you want to experiment with various pieces of tube gear? Do you have a need to match tubes? I have two tubed power amps and two tubed pre amps and I have three testers. But if you just have a tubed pre, buy tubes from a reputable seller. You may pay more but you are buying expertise and have some insurance there. Most people do not actually "need" a tester. But, if you are determined to have one I would suggest a calibrated Hickock 600 or 800 or a solid state B&K that has been calibrated. There are a lot of junk testers floating around ebay. Hamfests are a good place to look or buying from someone like Jesse Brent or S & D tube sales might be adviseable. Some come available here, but rarely at reasonable prices IMHO. Sometimes you luck up on ebay but you have to be very careful there. Don't attempt the ebay route without someone holding your hand. As Larryi suggests a cheaper emmisions tester may be a place to start. Even though these are limited in what they can do you can get your feet wet there.

Thank you for your responses. I recently purchased an Aesthetix Calypso and Quicksilver V-4's to replace my Pass X2.5 and X150 that were mated with a Raysonic 168. My tube list has grown from 6922,6DJ8, to; 12FQ7, 12BH7 or 12FQ7, KT-88 and 12AX7WB !! I thought it might be prudent to learn how to test the tubes in my equipment and what I'm buying to better match them. I'm not ready for a $2500 tester yet but $300-$700 is ok. Is there one unit in this range that will test all the tubes I use for leakage,microphonics and...? I want to roll tubes and it is becoming evident that to achieve the sound I may want will require trial and more trial. My intention isn't to buy and sell( but to buy and buy) so possibly a cheaper tester to start . I got a taste of what can happen when I connected the 168( Amperex US White Label PQ) to the V-4 's(KT-88) I had to put the EH 6922's back in because the sound had become too mushy.
