    Socket savers for Hickok 539C tester

    My Hickok 539C gets a lot of use. The 7-pin subminiature, 8-pin octal and 9-subminiature are so worn, I have to tilt the test tube until the line meter moves before I can be sure it connected. When I have dozens off tubes to test, this can become frustrating. The 7-pin has been replaced with a...

    why do New Sensor (Russian) tubes not read on tube (emissions) testers?

    There are a few threads that touch on this but nothing concrete. I have seen other posts about this phenomenon on Facebook and elsewhere, but wanted to make a thread. I have two testers (B&K 666 Dyna Jet and a Lafayette TE-50), both emissions based, that I’ve been running for years and keep in...

    Picking between two tube testers available...

    Hey. I have a few devices I've picked up over the years with tubes (and a box of used tubes) and wanted to get a tester for a while, even though I probably don't really need it. At any rate, saw a local posting this week with two models for sale and was wondering if anyone here knew which was...

    TV7 Tube Data

    Hi. I just bought a TV7 A/U from a guy on ebay who, now that the sale has completed, will no longer respond to my emails. The data book included has almost every tube that I need to test so far except one. I have a World Audio Design HD83 headphone amp. It takes ECL83 tubes. I can not find...

    Your own tube tester

    Does anyone here who doesn't repair gear professionally have their own tube tester. I have an opportunity to buy a Eico 667 in good working order. I am about to dive into building my first tube power amp and wasn't looking for this kind of gear - it just showed up. As new tube are becoming...

    Tube Matching - TV-7 vs Plate Current

    There are two methods commonly used to perform tube matching, using a tube tester or by measuring in-circuit plate current. The tube tester would seem preferable, but my TV-7 measures transconductance at a plate voltage of 150 vdc while the in-circuit plate voltage is nominally 440 vdc. So I...

    Weston Tube Tester Model 777 parts & issues

    Picked up a Weston multimeter 772 & 777 tube tester combo. I repaired the power cord for it and now I'm looking to find the short indicator bulb (My fault it broke!). After repairing the cord I had it up and running but then it stopped working so I took it out of its case and I must of put...

    question about Sencore Might Mite II TC-114 tube tester

    Good afternoon all, I'm restoring a Mighty Mite II Tube Tester (TC114 model). I have the user manual, which includes a schematic, and I've reviewed the TubeSound article on restoration of a Mighty Mite (it's a good guide, if anyone out there has one of these they are rehabbing). My question...

    Hickok 533 Tube Tester Question

    Howdy folks, I just picked up a Hickok 533 tester. The seller noted that the #83 tube had been replaced by solid state diodes. He did include a nos #83 tube in case I wanted to convert it back. I don't know whether or not it was recalibrated in that process. On testing small signal tubes...

    Sylvania self-service tube tester find

    Stumbled across this at Brimfield (weeklong, massive flea market in central Massachusetts). Brimfield has gone way up in price over the past 5+ years, so when I spotted it, I assumed the guy wanted way too much for it. Turns out he wanted a fairly reasonable amount for it and after thinking...

    uTracer Tube Tester Build

    I've been building again. I had just re-built and calibrated my B&K 707 Dyna Jet tester, which I've been very happy with. I had been looking around, though, for a reasonably priced instrument to do more in-depth tube analysis and matching and found Ronald Decker's uTracer and decided to give...

    Need to find Tube calibrator

    Hi all. I went to pickup a SCA35 and the guy mentioned he will sell the tube tester if I am interested. It happened to be a TV-10A tester. I promptly emailed Dan Nelson for calibration and I got a reply that he calibrates only TV-7. I read somewhere TV-10A/U is similar to TV-7. Serial number of...
