Tube tester?

Is this a good tube tester?
Do you guys have recommendations?

I need a good tester for 6h30, 6550 for my audio research

Can a tube tester tell if they are about to blow for example?

    The Hickok 539 or 750/752 series are some of the best. A tube can go bad at any moment, just the way it is.

    Are tube testers rather simple to use?

    Like most stuff, easy for some and not for others. You shouldn't have a problem.

    Do none of your audio buds have one?

    Reach out to Paul Hart and ask him, tell him what tubes you want to test.
    I had him work on my Hickok 600a, the guy knows he's stuff. He also sells testers that he has went through and brought up to snuff and fixed all that lost spec's.
    I can give you an email and phone number to reach out.

    Many old testers no matter how well they've been taken care of 50 to 70 years later they need work it's just the way it is.

    I can't talk my dad out of his Hickok 600a. He still uses it occasionally to service his test equipment and ham radio.

    Regardless of how well it's made, time isn't
    Kind. A refresh and calibration are in order
    to be accurate. But if you just use it once in
    A while to see relative tube health, it would
    Be just fine. I have a Hickok stashed away.
    Those are well regarded as also well
    documented. Repair and calibration onto
    are all over the web.

    Id recommend a B&K Precision 667 (solid state unit) . Nicely compact/small (compared to many) , super easy to use and accurate to the best of my testing and comparison to others such as the Hickok , etc over the last 10/20 yrs . ~ I do have other more pro/complete testers , but the 667 is my favorite for traveling to clients or sales where tubes need to checked . ~ I have two , one for travel and the second for home use when I dont want to breakout the big guns . ~ Both units still going strong and one has not needed calibration , the second needed mild calibration when first purchased , but nothing since . ~ Very nice units for the casual tester (or semi serious) , imo .
