EASY TUBE Tester 1.2

This is our very advance design, a tube tester with build in microprocessor control, automatic tube tester for beginner and professionals (not for heavy industrial use, but for audiophiles only), you don't need to operate a very complicated vintage tube tester just to test out a simple tube, this unit can test both emission(mA) and mutualconductance(uS) at the same time, it can also display both section of a dual triode testing result simultaneously, for which none of those vintage tube testers can. It can also test a power pentode in either Triode / Pentode mode.

Advantage : Light weight, small size, low cost, simple to use, no calibration needed , LCD readout display , keypad control , already fully assembled and tested with full parts and labor warranty, 1 year free software and hardware upgrade.

Disadvantage : envy by competitors

This unit have two modes of operation : Standard emission test / Tube matching test

For standard emission test, just press the button to choose the type of tubes and set the desired bias level for testing, then the display will show a very accurate reading of emission in "mA" and mutualconductance in "uS". If the tube is a dual triode, it can even shown the reading of both section at the same time, so that you can very easy compare the difference between two sections.

For tube matching test , also just press the button to choose types of tubes undergo matching process, and set the desired bias level for match, then the display will show the first tube under match's reading, just press a "Memory" button and the first read will record as references data for comparison, put in another tubes which undergo matching process, the display will show the "Reference" reading and "matching" tube reading at the same time as well as their deviations in percentage.

This unit is equipped with our special robotic adaptive programming technique for self-calibration and testing , no need for any adjustments like those vintage tube tester and will always gives out the most repeatable and accurate readings. (typical transconductance testing repeatibility within +/- 1% at 10000uS)

This tester can test almost all standard audio tubes with 8 and 9 pins, dual/single triode/pentode, and it can also test any special tubes with an external adapter, we also provide necessary information for you to made your own test adapter for other tubes types, but if you don't want to make it yourself then we can do it for you at a very reasonable cost. This unit can work with our STR (super rectifier) to test those big rectifier tubes.

Basic unit can test the following tubes and all their pin compatibles (6V filament)

6L6, 6V6, 6K6, 6Y6, 6G6, KT66, KT77, KT88, KT90, KT99, KT100, 6550, EL34, 5881, 6CA7, 6BQ5, EL84, 6922, 6DJ8, ECC81, ECC82, ECC83, ECC85, ECC88, ECC188, ECC288, ECC32, ECC33, ECC35, 12AX7, 12AU7, 12AT7,12AY7, 5814A, 5751, 6SL7, 6SN7, 6SU7...etc

With our special external adapter, can easily test those famous triode such as 300B, 2A3, 845, 211 , 45, 50, 811....etc for their transconductance and emissions.

If you already have our super rectifier STR-104 and STR-1001, then it can test the emission of 845, 211, 300B, 2A3, 45, 50, 866A, 3B25, 3B28, 1616, 8020, 836, 872A, and all their equivalents

(note: mutual conductance reading might have slight difference with different brand of testers, this is due to different testing conditions and circuit designs)

MSRP : $1680

Direct out of factory price : $880 only !! (Note : This unit is not designed for heavy industrial usage, just for audiophile only)

Industrial version with additional cost apply.

1 year free parts and labor warranty under normal operation conditions

1 year free software upgrade

(Note: Due to our below cost price and limited production capacity, this tester currently will only sell to local customers , and out of town customers who already own our audio products )
