For sale are 4x EL84 Telefunken tubes, matched quad. I bought them from a German Tubes specialist seller for a pair of Leak TL-12 Plus. However I had to return the Leaks due to issues. The Telefunkens arrived after I returned the Leak so they were never used. The tubes are new from old stock in the original packaging, without random <> in the Glas bottom. NOS. Measured by the seller with the Roetest V10 tube tester, the most professional tube test system currently available. The test reports are shown individually, the measurement result is stored in % in the fields marked in green. They come with each original packing box and a very nice Telefunken box to hold 4 tubes.

Amperex Holland EL84 6BQ5 Vacuum Tube Bogey ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Tested on an enhanced Triplet E3444 Laboratory Tester prepared by Paul Hart of Roswell, GA Industry Bogey transconductance = 11,300µmhos Industry Bogey plate current =48mA Results =11,300µmhos ~58mA 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.
