These tubes are brand new Sovtek 6L6WXT+ tubes that draw higher than normal plate current. We reject them in our matching process because most amps can not properly bias them so they would run too hot. These are good for those who work on their own equipment and will make resistor adjustments in the bias circuit to bring them into the appropriate bias range, or those who already have amplifiers with a very wide range of bias available. They test as new in all other respects and will carry our standard 90 day warranty.
This Sovtek 6L6WXT+ is modeled after the vintage RCA 6L6GC "Black plate". This 6L6 tube features larger plate dimensions and improved grid structure for increased power handling capabilities. It also features mica spacers with metal springs to eliminate tube rattle and microphonics. Sovtek claims it has 20 percent higher output than their 5881WXT.
