Telefunken ECC88 twin triode, made by the Telefunken works, Ulm, Germany.
This tube has a grey shield and declined getter support. The tube is manufactured in 1965. Long life version of a ECC88 tube. One of the finest E88CC; spacious, neural and very detailed sound image. I refer to the web for more information.
Note from the WEB: Like any other Telefunken tubes, these E88CC’s are very pleasant to listen to: liquid, euphonic, with a slightly warmer midrange than many other German tubes, which makes your sound experience smooth and non-fatiguing, and all that happens on a unbelievably realistic holographic sound stage, where everything feels bigger, wider and taller. Sound texture can be felt through infinite levels of details, laying on top of each other, both in depth and in width. So your quest for superb sound clarity can end right here. Lastly, it never gets old to say that no other brand is even close to these when it comes to low noise – Telefunken tubes are “extremely” quiet just as legend has it.
Test results
The tube is thoroughly tested. It has excellent test values that match the factory specifications very well and has balanced triode systems. The measurement data below illustrate that the tubes are matched and internally balanced.
