Telefunken E88CC-TK (6922) | Black Diamond Series Replacement Vacuum Tube Single Unit

The newly produced TELEFUNKEN E88CC-TK gold pin tube resurrects the transparent tone and harmonic impact of historical Siemens and TELEFUNKEN tubes. Whether it is installed in a phono stage or microphone preamplifier, this E88CC-TK will breathe new life into all audio equipment offering precise imaging, unmatched dynamics and a large full-bodied soundstage.

Also known as the 6922, the E88CC was originally targeted for test equipment and radar. The E88CC has medium gain, low noise and is a favorite for tight sounding audio input stages. There are some that will argue that the E88CC is the best sounding input tube ever designed. The E88CC is a dual triode tube like the 12AX7, but has a different pin configuration making it not a direct plug-in replacement. It is most commonly employed in amplifier designs where more clean headroom is desired. The medium gain characteristic of the tube and the low-noise design are part of why this tube sounds as good as it does in microphone preamplifier and phono preamplifier applications.
