CV3711 / N78 / 6BJ5 GEC

42.00 USD

Rare and valuable GEC CV3711 / 6BJ5 / N 78 (G.E.C.) new in box made in England for British Royal Air Force (aircraft parts). CV 3711 = N78 = 6BJ5. New in box, pristine condition. CV-3711 / 6BJ5 is very close to the EL84 with 6.3 volt and 0.64 amp and can replace EL84 with cv3711/El84 vacuum tube adapter socket (not available on dbTubes store). Many guitarists prefer this tube to traditional EL84 (adapter require).

WHY ?

A tube may have one, two, or three internal sections depending on the purpose of the tube; somtimes these sections are all the same, sometimes they are different. Due to manufacturing and material tolerances, there may be slight differences between the original specification and the actual tube. Tube matching tests each one of these internal sections and selects tubes, compared to original specifications at manufacture, for balanced performance and good sound.

HOW ?

All our tubes are tested by us prior to packing on our Stark, AVO, Simpson or RF Laboratories Inc. calibrated testers. On request for tube matching, tubes are matched for Mutual Conductance in Micromhos and Plate Current in Milliamps on our Amplitrex or Radioelec Duovac testers, with results printed for each  individual tube. Certain tubes difficult to test are matched for Mutual Conductance in Micromhos only on one of our regular calibrated testers. On request we can also test for Microphonics.
