Amplitrex AT1000 is in the house!
Have just taken delivery of an Amplitrex AT1000 Eletron Vacuum Tube Tester.
It is of superb build quality & does indeed look like a portable nuclear detonation device from the movies. It weighs approx. 8.3kg (18.3lb) The sockets are tight & do bite hard on the pins. I think I will order matching socket extenders. The unit works out of the box & is preloaded with many baselines. I can already see that I have been duped on a pair of rare Siemens E83CC gold pins which are measuring under baseline tolerances. I will be contacting the seller who sold me these tubes! I have also performed a couple of quick tests on some GL 12AX7 reissues with approx. 1500hrs on them & these appear to be a bit variable as well! Once I load the USB driver, hook up the PC & have a bit of a read, I will run some more comprehensive tests & post my findings. So far this looks to be a great device. |

Thanks for the update Steve. I think one of these and some nice tube amps are in order. Looking forward to some real world tests.

Steve.......Thanks for the feedback on the Amplitrex AT1000. From all that I have read on the tester, performing tests manually provides the most accurate and repeatable results. Were you using the auto test feature when testing the Siemens and Gold Lion tubes?
I am quite interested in the Amplitrex AT1000. I will be following your comments with great interest.

I understand you can upload/edit your own baselines for tubes where you have a specific manufacturer's published specification. eg. TFKs are generally +/-15% even if they are good & show no leakage. I need to sit down & spend some time with it & hope to start by reviewing the supplied CD this evening. Last edited by MyPal; 11-14-2012 at 01:28 AM. |

Had another play this evening, mainly with the software. The Tube Tester software works but it is buggy & easy to trip up & crash.
I re-tested E83CC gold pins. 2 x Siemens & 2 x TESLA. Multiple tests give consistent results. Attached are test result images for the Siemens which I screen scraped. Reports print equally well. Please feel free to interpret & comment. Still learning. Last edited by MyPal; 11-20-2012 at 08:50 AM. |

Test results for pair of TESLA E83CC Gold Pin.
For some reason the 2nd emissions test kept on crashing the app, but was testing OK. |
