This cutting-edge automatic digital audio tube tester offers a diverse array of robust testing features housed in a compact unit. It includes gentle-touch buttons, automatic self-calibration, waveform testing, consistently stable digital readouts, and accurate tube matching capabilities represented in percentage values. Its user-friendly design streamlines tube testing, catering to users of varying expertise levels.

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 ( noise level > 10mVrms can be detected on display)

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 in ATT3.01 ) or (6SJ7 in ATT3.02 ) and all their pin compatibles....( DHT / rectifier tubes with our optional extension test modules, with add-on UTC-1 universal tube adapter can test even more types of tubes). 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 ( arcing or short circuit conditions happen <200Vdc from plate to grid can be detected)

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 damaging the tester if remove it in a short while.

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.

Tube Converter #3

Can be used in the 6L6 position, to be able to test different types of tubes (E282F, 6AH6, 6AK6, 7233, D3A, E810F, CK6485 and all their compatibles) + $150

---

UTC-1

Universal tube adapter, which can let you self-configure 6 pins (G, K, P1, P2, F+, F-) , in order to test whatever tubes which can fit into one of the 3 different sockets. +$200

---

Note: Regular version is for audiphile / retailer / showroom / DIYer use only, not intented for super heavy duty industrial usage , which typically will perform over testing of 1000 tubes per day

Optional : Heavy duty industrial version include enhanced heavy duty components upgrade and one set of socket savers , ( one 8 pin octal and one 9 pin small socket saver ). For industrial usage, testing should be perform with the socket saver, and just change them when it become defective, this can prevent the possible wearout of the original sockets ( + $300 )
