This is not a listing about audio tubes but an invitation for you to hear the sweetest voice on Earth. No other tubes can deliver vocals like the Mullard's, whether they're from. Blackburn or Heerlen, and that's a fact. These E88CC tubes are particularly special because they have the very rare dimple disc getter and are being hunted to near extinction by audiophiles and sound professionals. Like a warm British jacket of the finest tweed, these glorious tubes have an attractive sweet warmth in their midrange and lower regions.

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 human voice, especially female voices, with haunting realism. Full disclosure from your peer audiophile: Mitcham E88CC's are my go-to tubes for listening to Maria Callas and Frank Sinatra and I refuse to use other tubes. Mitcham Mullard's are also known to have an attractive sparkle at the top with rich bass...

Now we know where that "warm British jacket" comes from! Both tubes tested NOS (100%+ nominal mutual conductance) on a Mercury 2000 tube tester with the following result (mutual conductance in uMhos and percentage of nominal).

15,000/ 15,750 (120%/126%). 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 would 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. We treasure this pair also because of the pristine condition of both tubes - nearly 100% of the paint and lettering are well retained.

The identical Mitcham date code etched in glass is also perfectly visible. (7L1 = E88CC, R = Mitcham, 0 = 1970, G = July, 4 = 4th week of the month).

This pair of tubes will be packaged in the Original Mullard tube boxes.
