Description

New Gain Matched Pair of Mullard 12AU7 / ECC82 Reissue Vacuum Tubes

The Mullard 12AU7 has a warm and detailed sound that is great for McIntosh amplifiers or any Hi-Fi low-noise circuits (and for any amplifier that calls for 12AU7, ECC82, 6189 etc. for that matter).

Will work in place of: 12AU7, 12AU7A, ECC82, 12AU7WA, 6067, CV4003, 5814

Testing and/or Matching

At VIVA TUBES, all of our customers get the same high standard of testing and matching. Some sellers charge more for premium matches but we believe all of our customers should get the same level of quality and service. 

Tubes are tested and/or matched at full operating voltage with regulated power supply on a Maxi Matcher tester for general mutual transconductance (Gm). In addition, power tubes are tested/matched by plate current (Ip) and preamp tubes are tested/matched by gain. Rectifier tubes will be tested for emissions on a calibrated military grade tube tester. 

Our goal is to match within 5% with an upper limit of 15% (15% is the industry limit to consider a set).

Hand written test data included.

Note that we do offer a few models which are tested & matched at the factory. They will be matched by the same parameters (Ip & Gm) but to the manufacturer's standards. Factory testing will be indicated in the item title and description. 

Guarantee

We offer a minimum 90 day guarantee covering functional defects - including noise unless otherwise stated. The guarantee period begins the day you receive your order.

    Installed originally on my loxjie p20

    It sounded great, but now I put 1 in my xDuoo amp and it sounds SOOOOO much better than the stock one. I'm going to have to pick up another single to keep the matched pair on my Loxjie.

    Great overall sound, relaxed presentation but with all the details present. The real bonus if the depth of the bass!!!
