Sophia Electric™ EL34-ST tubes
This patented Sophia Electric coke-bottle EL34-ST (long life version) tube has the richest tonality & the best musicality, a cure for any plain sounding EL34 amplifier.
Sophia Electric EL34 tube is a direct replacement of vintage Telefunken from Germany, or Mullard from UK. It is a premium upgrade choice for amplifiers currently using Chinese EL34, Russian EL34 tubes or Eastern European EL34 tubes.
Not all tubes are created equal.
