Description

The Telefunken ECC83 long plate tube is manufactured in the sixties in the Telefunken plant in Berlin. The pair is thoroughly tested and has excellent test values that match the factory specification very well. They are paired and have balanced systems. Very strong tubes! 

Sonics

Like other Telefunken tubes, these ECC83’s are very pleasant to listen to: liquid, euphonic, with a very neutral midrange, making your sound experience smooth and not fatiguing, and all that happens on an incredibly realistic holographic soundstage, where everything feels bigger, wider and taller

Designed for high-end amplifiers and preamplifiers, Telefunken ECC83 offers high gain with ultra-low noise and a sound signature that is highly regarded and often described as open, neutral and spacious. If you’re looking for the reference tube sound, look no further. It is without a doubt the most sought after vintage tube and the one cherished by audio professionals and enthusiasts.

I refer to the web for more descriptions of the sound properties. Excellent preamp valve, low noise so very good in phono stages.
