Art Audio only sells Grade A Tubes from Sophia Electric. Please specify if you need matched pairs or quads in purchase notes.
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.
Art Audio does not stock Sophia Tubes but Sophia will drop ship directly to you for us. Free Shipping on all order and they typically ship within 48 hours.
We do need to check inventory. If Sophia is out-of-stock you will receive a full refund.
