New Matched Sextet (6) Linlai E-6SN7 Globe-Balloon Black Plates Vacuum Tubes

New Factory Matched Sextet of Linlai E-6SN7 Globe Shaped Vacuum Tubes 

Linlai is a small but growing premier manufacturer of vacuum tubes. Spun off from the well respected Psvane, Linlai took some of their best engineers with them and it shows. This is an absolutely magnificent tube. It is the very first antique style globe preamp tube available in the modern market and we aren't sure why it took this long. The glass makes for the smoothest transmission of electrons possible which translates to mind-bogglingly good tone. Sextet that with black plates and gold-clad pins, it's hard to find anything that even comes close. 

Note - These tubes are much taller and wider than a typical 6SN7 and will only fit in amplifiers with large tube slots and ample vertical space. 

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.
