Description

New Gain Matched Pair of Electro-Harmonix 12AU7 / ECC82 Vacuum Tubes

Built around the original GE 6189; this is a low microphonic, industrial-grade 12AU7. This tube has a very clear and warm sound that was built to last. This is a very linear tube which sounds great at any volume or in any amplifier making it a versatile workhorse tube. The 12AU7 is interchangeable with a variety of tubes including the ECC82, 6189, and E82CC. This is the standard pin version.

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.
