No quads available, only singles and pairs.
The RFT EL34 vacuum tube can also been found labeled Siemens, Telefunken, Haltron and other brands. Our current batch of power tubes are labeled Haltron, Siemens, and Trigon. Although we have pairs available, due to limited quantity we are offering matching by plate current only, not by branding/logos. For example, a matched pair could have one "Siemens" labeled tube and one "Haltron" labeled tube. The RFT EL34 tube is an outstanding value for a NOS EL34 tube. They are German production from the 70's and 80's.
From our review: "These tubes are extremely warm sounding and if you have one of those amps that sound thin at lower volume levels, these should take care of that problem in short order. Midrange response seemed slightly skewed toward the bass side. This is no doubt where the extra warmth is coming from. The high end was smooth and clear without a trace of harshness."
