Description
New Plate Current Matched Pair of JJ 7591 Vacuum Tubes
There is finally a reliable 7591 that rivals the originals. These JJs are an excellent choice for your old Scott amplifier as well as many others that used the famous old 7591. The vintage 7591s are almost impossible to find these days, even back in the day only a few companies produced them for limited years. With the new JJ 7591s you can bring old amps back to life.
Will work in place of: 7591, 7591ATesting 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.
