1201A / 7E5

4.00 USD

Mint boxed loctal-based triodes manufactured in United States by AMC. These glass metal based tubes are designed for high frequency circuits with low inter-electrode capacitance and relatively high transconductance. Economical in filament current consumption, these tubes may be used as sharp cut-off voltage amplifiers. Entirely silvered by gettering, these tubes are printed in white 1201A AMC MADE IN U.S.A., with boxes in black, white, orange and gray printed 1201A.

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.
