United Electronic - 12AX7WA / E83CCWA vacuum tubes 2-set Audio component

Beautiful and very rare pair of 12AX7WA gold pin United Electronic selected with AVO 163e curve tracer valve tester. They are the perfect replica of the legendary ECC803S Telefunken manufactured by TESLA, formerly Czechoslovakia, with very small modifications. The microphonics is very low as is the noise, and they deliver a superb sound comparable only to Telefunken and to some Mullard for military applications. The tubes are stamped with a number 73-34 meaning year 1973 week 34 and in white Made in Germany but that is only for commercial reasons. They are a pair of NEW tubes only partially run-in and they are part of my private stock with about thirty hours on my phono preamp. They are also famous for their robustness and longevity, which in hi-fi use exceeds ten thousand hours without any drop in performance, Naturally I cannot provide any warranty and no returns are accepted.
