  1. ECC 803S Telefunken Gold Pin High Mu Twin Triode Tube Made In West Germany E83CC, 12AX7 (NOS/NIB)

    ECC 803S Telefunken Gold Pin High Mu Twin Triode Tube Made In West Germany E83CC, 12AX7 (NOS/NIB)

    $1,349.91

    The ECC 803S (ECC803S) Telefunken Gold Pin High Mu Twin Triode tube is RARE and difficult to find.  The ECC803S is a very low noise, special quality 12AX7, made with the old-style Telefunken German precision. These have the ultra wide bandwidth of the Telefunken ECC803s, but also have nicely matched internal triodes, gold pins, and have been carefully factory-screened for low noise.
