Description
This is a pair of Telefunken esoteric ECC802S tubes in unused condition.
This pair Telefunken ECC802S is a made in the Siemens & Halske plant in Munich. When Telefunken of Western Germany closed their production factories they still had a demand for their ECC802S audio tubes. Where better then to source an alternative from Siemens Halske plant in Munich? And from this plant they chose the best, the famous triple-mica, double post E82CC; one of the finest ECC82. Telefunken ordered a limited supply of these beauties for this Telefunken non-diamond bottom ECC802S. To comply the very strict specification of the ECC802S, Telefunken has undoubtedly used selected versions of the E82CC only. I offer this pair for a lucky audiophile to enjoy!
The etch code Dø3 # 9G / Dø3 # 9F on the glass indicates that it was manufactured in Munich in July & June 1969. The tube has triple mica reinforcement and a round halo getter. The tube has excellent test values that match the factory specification very well and balanced systems. The properties of this tube are widely known. I refer to the many threads on the web for more information.
Note from the web: “This is an E82CC, made by Siemens, and famous for a vivid and clear midband, and perhaps the best dynamics ever. Ever so slightly relaxed on top. Super bass response.”
Sonics
Excellent valve, low noise, low microphony, smooth extended highs, very good in phono stages.
ECC802S: balanced and clear sounding with liquid midrange, recommended!

The tubes have been tested carefully with the official Telefunken test set-up and our sophisticated test equipment. Please read our testmethod for the ECC82 tube family.
