Amplitrex AT 1000 Vacuum Tube Tester
Price: US $2300.00

I have my collection of about 3500 vacuum tubes listed for sale, so I am also offering my Amplitrex tube tester for sale. If you are not familiar with the tester, you can go to the Amplitrex website.


I sent this tester to Chris Terraneau in February 2014 for a factory update. A new generation microprocessor (18f4520) and updated firmware (V2.21) were installed. A new, more robust, overload relay was installed as well as the 7 pin socket. A socket saver was installed in the 9 pin socket.


The original tube data was version 033. You can see a list of the tubes on the Amplitrex website. I have added 14 tubes to that list and uploaded the file to the tester as version 063. Also included are the 3 cables to connect to tubes with various sizes of top caps. There is also a power cord and a cable to connect to a computer for remote operation. The is one extra adapter for some special tubes, and the original CD with all of the operational information.


Also included is a Sony VIAO 16\" laptop computer and a USB cooling platform. The computer is loaded with the Tube Data file, and the Tube Test file. With the computer, you can print the results of each tube test. The printout is very complete and gives a wealth of information with which you can judge the quality of each tube. You can also print out tube graphs. The computer has the original system installation disk, so you don\'t have worry about a disc failure.


The tester is fitted into a very sturdy \"Pelican\" case. When I am not using the tester, I keep it and the box of accessories in a plastic container to keep out dust and insects.


Tube rollers take note. This will test the 14 most popular amp tubes that the Orange VT 1000 tests. In addition there is a dedicated noise test system built into the Amplitrex. Bang on your old KT 88 and listen to it ring.
