Description

This is a pair of Telefunken ECC802S made in Ulm Germany. 

The properties of this tube are legendary and widely known. I refer to the many threads on the web for more information. Telefunken produced a very limited number of these beauties. 

 The tubes have the typical plate structure of the Telefunken ECC802S with reinforcement and of course the diamond bottom. The tubes are most likely unused and have NOS test values that match the factory specification very precisely and balanced systems. 

This pair is a real bargain, please compare the  with other suppliers!

Sonics

Excellent valve, low noise, very smooth extended highs, very good in phono stages. 

ECC802S: balanced and smooth sounding with liquid midrange, recommended!

Please read our test and shipping policy before buying !

Test method & results

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.
