Tube Summary

No other tubes can deliver vocals like the British made Mullard tubes, from ECC88 to E88CC to E188CC every variant of these can make your audio system sing like an angel, and that's a fact. These Mitcham E88CC's are extremely hard to find today and are becoming the darling of every serious audiophile.

Sound Characteristics

The overall tonality of Mullard E88CC tubes is warm and lively with a very spacious sound stage. "Like a warm British jacket of the finest tweed, these glorious tubes have an attractive sweet warmth in their midrange and lower regions."  This is how the experts on audiotubes.com describe the sound signature of British-made Mullard tubes. The top end is silky and pleasant and doesn't get rolled off. They retain a fine sense of "air" at the top, and the upper midrange is smooth and liquid. These tubes reproduce the human voice, especially female voices, with haunting realism. The Mitcham Mullard tubes are also known to have an attractive sparkle at the top with rich bass...now we know where that "warm British jacket" comes from!

The cherry on top: the lovely blue tip, a statement of the tube's proud history of being selected to be used in mission-critical military or medical devices. The sonic differences (for the better) you are getting from the blue tip are enhanced clarity/details and ultra low noise.

Appearance & cosmetic condition

We treasure this tube also because of its pristine condition - 100% of the paint is intact, and the Mitcham factory's date code etched on glass is perfectly visible: 7L1 R4D3 (7L1 = change code; R = Mitcham, 3 = 1964, G = July, 4 = 4th week of the month.)

Professional testing & sound evaluation

The tube tested Strong (80%+ GM) on a Mercury 2000 tube tester with the following result (mutual conductance in uMhos): 11,800/10,100 (94%/80%) 

Good tubes start at 7000 and new tubes (incl. NOS/NIB) 12,500 - 13,000, and the Mercury 2000's rated mutual conductance (nominal) for new tubes is 12,500. Test result can also be seen in the pictures. In case you wonder what all these numbers mean to your sound experience, it's actually quite straightforward: mutual conductance directly translates to a tube's ability to amplify sound, so the higher the numbers the stronger.
