Description
New Gain Matched Quintet of JJ 12AU7 Vacuum Tubes
One of the cleanest and prettiest sounding 12AU7 tubes that are out right now. They based this design off of the famous JJ 12AX7 which is so good that many guitar and audiophile amplifier brands choose to use them as stock tubes including Fender. With only about 20% of the gain of its 12AX7 counterpart, the cleaner sound shines through.
Will work in place of: 12AU7, 12AU7A, ECC82, 12AU7WA, 6067, CV4003, 5814Testing 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.
