Auction is for one (1 pcs) extremely rare geniune Telefunken 6080 / 6AS7 / 5998.
This tube is very scarce. You can find many other types rebranded Telefunken 6080 like General Electric, RTC France, Sylvania, ... All of them come in original Telefunken boxes.
Someone who is not deeply interested in tube production details for years could make mistake easily.
This one is made in Ulm tube plant and it's clearly different to fakes in many details. The most important details are unique Telefunken's thick ring getters, two of them.
The tube is tested with 100V on plates and -24V on grids. This tube tests 130/136 mA, very strong example, like NOS, with lot of life left.
Please pay attention that guiding pin is broken as it is shown on photos!
