Tested on an enhanced Triplet E3444 Laboratory Tester prepared by Paul Hart  of Roswell, GA

Industry Bogey plate current = 48mA
Results =9600µmhos ~38mA
The measurements in this listing were taken on a Triplett 3444 modified to test the tube as an amplifier in accordance with RMA/EIA specifications, utilized by all US and most foreign tube manufacturers.  This tester applies test conditions for this tube  (including the precise filament voltage) and then measures transconductance (gm) in accordance with the engineering definition of gm. Tubes may also be operated under the test conditions for extended periods to be sure that it is stable.  A tube must be tested in this manner to compare its test results with the manufacturer’s original intent or with other tubes of the same type. Most tube testers do not apply the test conditions required or conduct a valid gm test. For more details on the test and our test equipment, please contact us.
