Siemens & Halske pair gold pin CCa Germany 1960s [Expired]


no longer for sale

One pair Siemens & Halske gold pin CCa tubes made in Germany in 1960s. Single ring getter, grey plates.  Same etched codes: 32155 and Aϕ 1#  2A (partly rubbed out on one tube).  Tyler at tctubes tested the tubes with Amplitrex AT1000 in October 2015, and said they "tested well". Test results are on boxes (see photo). On this basis, I rank the condition of the tubes as Very Good. The tubes have not been used since then.   Siemens & Halske CCa tubes are rare and considered by many to be the very best of the 6DJ8, 6922, 7308, CCa group.  Brent Jesse (audiotubes.com) says: "whew, these babies are scarce/these gold pinned gems are about as good as it gets in 6DJ8-land/awesome audiophile tubes/ 10,000 hour heater life-expectancy". Brent lists these tubes from the 1960s at $299.00 per single tube.  On the tube museum website (tubemuseum.org), CCa tubes from the 1950s and 1960s are said to be: "Rarest and most sought after CCa/ Most realistic sounding holographic soundstage, pure seductive magic/ Complex symphonic images emerge effortlessly".  I no longer have my phono preamp (Aesthetix Calypso) which used a pair of these tubes, and am reducing my collection of spare NOS tubes.
