This is a super advance automatic digital audio tube tester, which eqipped with the following powerful testing capabilities in a compact unit, soft-touch virtual buttons, automatic self-calibration, waveform testing and tubes matching in %. Super simple tube testing for everyone !!

(powerful dual core ARM CPU with 12bit measurement resolution)

1. Gain test (0 - 120)

2. Gm (transconductance) test 0 - 100mS ( 100000 uS)

3. Noise test (0 - 10V on display), also eqipped with RCA output for external monitor / testing

4. This tester can test almost all common audio tubes 6SL7, 6SN7, 6SU7, 6AS7, 5691, 5692, 12AX7, 12AU7, 12AT7, 12AY7, 12AZ7, ECC32, ECC33, ECC35, 5814, 5751, 6L6, 6G6, 6V6, 6Y6, 6F6, 6K6, 6CA7, EL34, EL84, 5881, KT66, KT77, KT88, KT99, KT100, KT120, KT150, 6550, 6BQ5, 6922, ECC88, ECC188, ECC288, ECC81, ECC82, ECC83, 6H30, 6080, 6CG7, 6FQ7, EL32, CV1052, VT52, 7591, 7868 and all their pin compatibles....( DHT / rectifier tubes with our optional extension test modules ).

For tubes not mentioned on the above listing, if they are 6V filament and pin compatibles with one of the tube sockets, then the test can be performed with this tester.

If there is no pin compatible tube sockets for the tube want to be tested, you can just build your own converter or order from us, to test any audio tubes either single pentode, single triode or dual triode within the tester's filament voltage range, just wire the corresponding pins of the tube under test, to matching one of the sockets pin configurations

5. Automatic A. I. self calibration features. This unit will performce self calibrate when power on. You can also perform self-calibration afterwards by pressing the three touch buttons at the same time.

6. Gassy / Grid leak tube indicator

7. A/B selector , set to A for single pentode, set to A or B for dual triode testing

8. Fully automatic biasing for gain testing. Just select corresponding tube models for GM testing.

9. Regulated 200V power supply with 150mA current limit and short circuit protection, can test short circuit tubes without the fear of damage of the tester

10. High stability and reliability, high precision and repeatability with a full color TFT LCD readouts.

11. Self-explanation panel, anyone with just little bit of knowledge on tubes can perform the testing, no more steep learning curve. Easy and well guided user manual included. No calibration is required and trouble free.

12. Tube matching in Gm and Gain, just press memo to record the first tube under test, then put in the next tube for comparison. The display will show the difference in % (anode current + gain / GM) between the reference tube and the tubes under test.

13. Real-time waveform display to check any abnormals in the tube under test, which might be slip through all those old school or out-dated design tube testers.

14. one year free parts and labor warranty and full technical support

Available in either white or black top panel color of your choice.
