Description
New Gain Matched Quintet of Electro-Harmonix EF86 (6267) Vacuum Tubes
There is finally a new production EF86 and a great audio pentode for many different applications. The vintage EF86s, while having great tone, are notoriously plagued with noise. Electro-Harmonix has found a way to keep the noise and microphonics down in this reiteration. This tube will work in any circuit intended for EF86 or 6267.
Will work in place of: EF86, 6267, EF806STesting 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.
