The RFT EL34 Short Base is a rare and sought after EL34. RFT was a East German manufacturer of tubes and while later production RFT made tubes are not known for their quality, the earlier production items including the EL 34 short base were exceptional. The short base EL34 is a very linear tube that focuses on the little details in your music. It is more similar to the sound of a Telefunken 12AX7 then a Mullard 12AX7 if that means anything to you. While controversial I actually prefer this tube to the Mullard XF2 EL34. We have a single matched pair available.
All tubes are tested on a AT1000 computerized tube tester at real world operating voltages (400 volts in the case of the EL34), one tested tubes are also matched at those voltages. For power tubes we match based on EM first and then GM. For small signal tubes we match based on GM then EM.
Please be aware that vintage vacuum tubes are antiques and carry no guarantee or warranty. We provide a sheet explaining what you purchased, your test results for your tubes, and if need be can provide photographs of the tube on the tube tester before we pack and ship them.
