This is our new 2017 revised advance design, a tube tester with build in microprocessor control, automatic tube tester for beginner and professionals, you don't need to operate a very complicated vintage tube tester just to test out a simple tube, this unit can test both emission(plate current in mA) and dynamics Transconductance(AC Gain, most accurate and meaningful measurement for audio tubes) at the same time, it can also display both section of a dual triode testing result simultaneously, for which none of those vintage tube testers can . This newer version can test 2.5V , 5V and 6V audio tubes and rectifiers. Test signal frequency is 10Khz, which can eliminate the noise interference by 60Hz hum signal and give a much more accurate and stable readings, and best simulate the actual audiophile amplification operation condition. Emission mA reading also enhanced from 1mA/step of to 0.1mA step, this new model emission current (Plate current) display range from 0.1mA - 100mA.
Advantage : Light weight, small size, low cost, simple to use, no calibrations needed , LCD readout display , keypad control , already fully assembled and tested with full parts and labor warranty, 1 year free software upgrade.
Disadvantage : envy by competitors
This unit have two modes of operation : Standard emission+ transconductance test / Tube matching test
For standard emission test, just press the button to choose the type of tubes and set the desired bias level for testing, then the display will show a very accurate reading of emission in "mA" and dynamics transconductance in "uS". If the tube is a dual triode, it can even shown the reading of both section at the same time, so that you can very easy compare the difference between two sections.
For tube matching test , also just press the button to choose types of tubes undergo matching process, and set the desired bias level for match, then the display will show the first tube under match's reading, just press a "Memory" button and the first read will record as references data for comparison, put in another tubes which undergo matching process, the display will show the "Reference" reading and "matching" tube reading at the same time as well as their deviations in percentage.
This unit is equipped with our special robotic adaptive programming technique for self-calibration and testing , no need for any adjustments like those vintage tube tester and will always gives out the most repeatable and accurate readings.
This tester can test most of the audio tubes with 8 and 9 pins, dual/single triode/pentode, and it can also test most of other tubes with an external adapter (optional), we also provide necessary information for you to made your own test adapter for other tubes types, but if you don't want to make it yourself then we can do it for you at a very reasonable cost.
Basic unit can test the following tubes and all their pin compatibles (6, 5 and 2.5V filament)
6L6, 6V6, 6K6, 6Y6, 6G6, KT66, KT77, KT88, KT90, KT99, KT100, KT120, KT150, 6550, EL34, 5881, 6CA7, 6BQ5, EL84, 6922, 6DJ8, ECC81, ECC82, ECC83, ECC85, ECC88, ECC188, ECC288, ECC32, ECC33, ECC35, 12AX7, 12AU7, 12AT7,12AY7, 5814A, 5751, 6SL7, 6SN7, 6SU7, 6AS7G...etc
300B 2A3, 45,1616, 3B27, 3B28, 836, 816....etc. (note: rectifier tubes only have valid emission readings )
(free bonus test adaptor for rectifier tubes like 5U4G, 5AR4 , 274B....etc)
Emission test range : 0.1mA to 100mA (with 0.1mA / step resolution)
Testing voltage : 200V / 250VDC max
Testing frequency : 10Khz sine wave
Upgrade Option : Tube noise test for additional cost of $400 only (super low noise power supply upgrade, with added pair of RCA output for noise monitor and measurement, additional selector for regular / noise testing)
(note: Dynamics transconductance is the best way to test a tube , because it simulates the real operation condition for music reproduction with AC test signal, in while vintage tester cannot do (they only test for emission or mutualconductance) the reading might show differently between different brands of testers, this is due to different testing condition, but this will not affect any tube matching accuracy)
Customer Feedback :
From Min: Your tester is SO easy to use even for someone like me, who knows nothing about tubes ( I really like the sound of tube though). it really is great product for testing few simple tubes for home use.
From Robert: I used the tube tester and found it very easy to use and reproducible. A very useful device
