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. 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, 5881, KT66, KT77, KT88, KT99, KT100, KT120, KT150, 6550, 6BQ5, EF86, 6267, 6922, ECC88, ECC188, ECC288, ECC81, ECC82, ECC83, 6H30, 6080 and all their compatibles....

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. Unit comes with 1 year free parts and labor warranty and full technical support

(optional : 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. 4A, external 12V power supply and adapter cable included )
