ECC88 / 6DJ8 HALO GETTER

59.00 USD

The best sounding double triode pre-amp tube around, manufactured by Telefunken. These fine miniature glass 9 pin amplifier tubes come with gray plates, thick mica spacers, and top halo getters. We believe the manufacture may have been subcontracted to General Electric, Siemens or Philips in USA or Europe in the 1970' or 1980's. They are printed in white with Telefunken logo, ECC88. Boxes are standard Telefunken blue and orange, printed ECC88.

LEARN MORE 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.
