***
The measurements in this listing were taken on a Triplett 3444 modified to test the tube in strict accordance with RMA/EIA specifications, utilized by all US (and most foreign) tube manufacturers.  The test is of actual transconductance (gm) with the tube under the quiescent conditions specified for it.  Most tube testers cannot not apply the test conditions required to provide a valid gm test; in addition, many provide a surrogate gm test.  For more information, please contact us.
