This is our newly 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.... (for tubes not in this list, 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 want to test matching one of the socket will do, the test circuits are all the same)

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% accurancy. User can easily check cal. reference before test to make sure equipment in top notch condition.

6. Gassy / Grid leak tube indicator (when set to noise test, lit up means tube has grid leakage current or gas)

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

8. variable bias 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 can test a vacuum tube in seconds, no more steep learning curve. Easy and well guided user manual included.

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

(optional 300B test module : can test 300B / 2A3 / 811/ 45 / 50 / 274B / 5U4G / 5AR4 / 6X5 ......and all pin and filament compatible tubes , variable filament supply voltage from 2V to 12V variable in 0.1V step, max. 4A, external 12V power supply and adapter cable included ) + $380

(optional 845 test module : can test 211/845/805/811/300B / 2A3 / 45 / 50 / 274B / 5U4G / 5AR4......and all pin compatible tubes , variable filament supply voltage from 1V to 12V variable in 0.1V step, max. 5A, external 12V power supply and adapter cable included ) + $680

Converter #3 use in 6L6 position, can test much more different types of tubes (E282F, 6AH6, 6AK6, 7233, D3A, E810F, CK6485 and all their compatibles) + $150
