Description

Mullard E88CC twin triodes, Mitcham, United Kingdom.

These tubes have a dimple disk getter getter and both are manufactured in Januari 1972 by Mullard Mitcham UK. They are the long life version of a ECC88 tube.

The dimple disk version of Mullard is known a very fine E88CC; with a liquid, creamy and very detailed sound image. I refer to the web for more information. 

The pair is NOS. Both tubes are thoroughly tested. And the matched pair has excellent test values that match the factory specifications of a new tube very well and and both tubes have balanced systems. See test results below.
