Description
Brand New Factory Matched Quad of Svetlana SED SV-572-10 Vacuum Tubes
Out of the three models of SV572, this SV572-10 offers the lowest transconductance of 4,500 Gm and lowest plate resistance of 2,100 ohms. The SV572-10 offers a higher power (125 Watt rating) option to classic 211 or 845 tubes.
* PLEASE NOTE THAT THESE RUSSIAN-MADE SVETLANA 572 TUBES ARE NOT PLUG-AND-PLAY COMPATIBLE WITH AMERICAN EQUIPMENT; THEY DO NOT HAVE THE TOP CAP CONNECTION LIKE THE AMERICAN 572B VERSION. THEY ARE OTHERWISE THE SAME TUBE.
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.
