Mullard 12AU7 ECC82 Box Plates Wrinkled Glass Mitcham 1959 Near NOS

No other tubes can deliver vocals like the Mitcham Mullard's, and that's a fact. These ECC82 tubes, especially the early 1950s ones, are extremely hard to find today and are becoming every serious audiophile's darling.

The overall tonality of Mullard ECC82 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. 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 British made 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!
