Perform Gain / Gm / Noise test on audio tubes

Suggest retail price : C$1,880 (Audiophile version)

Direct out-of-the-factory price only CAD$980 Untitled Document [US$ 882]


This is our advance designed audio tube tester, eqipped with the following powerful testing capabilities in a compact unit

1. Gain test (0 - 199.9)

2. Gm (transconductance) test 0 - 199.9mS( 199900 uS)

3. Noise test (0 - 199.9 mV on display), also 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 and all their compatibles....( DHT / rectifier tubes with our optional extension test modules ).

For those tubes did not mentioned on the above listing, if they are 6V filament and are pin compatible with one of the tube sockets, then the testing can be performed by 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. Easy calibration by just one calibration pot with digital meter indication, typical cal. to +/- 0.5% of 100.0 will be good enough for testing with 1% in the matching accurancy. No more expensive and time consuming calibration as those vintage tube testers.

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. variable bias (max. bias setting is around -0.8V) setting for test under whatever desired plate current condition

9. Regulated 200V power supply with 100mA current limit and short circuit protection, can test short circuit tubes without the fear of damage of tester

10. High stability and reliability, high precision and repeatability with all digital 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.

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