USD $‎349.95

We have limited stock of NOS Telefunken ECC83 (12AX7) preamp tubes that are the much sought-after smooth plate construction. They have several characteristics that identify them as the real deal, most notably the diamond pattern in the base with the bottom of the diamond pointing to the space between pins 1 and 9.

What's the big deal with Telefunken vacuum tubes? Aside from the fact that they are now extremely rare, Telefunkens have long been considered both the best sounding and longest lasting tubes of their type.

Amazing in all ways


Amazing tube, lovely vocals, thumpy base but still controlled. Has the best midrange of all the tubes I currently own. Just perfect :)
