EL34 Telefunken, winged plates, double-O getter, “Lab sample”, x-rare! one pair (2)
Out of stock
This is the strongest testing pair of EL34 we ever had on our tube tester. The meter actually peaked on the right side….
These are Telefunken EL34 featuring double-O getter, winged plates and dark brown bases.
Both carry a Telefunken sticker “vertrauliches Labormuster” = “confidential lab sample”.
These may have seen some lab use but they were never used in a real application or amplifier.
You won’t find these any where else. These are as rare as it can get and are serious collector items!
You will receive one pair/two pieces. Both tubes are tested and are in excellent working condition.
