GT-6L6-GED-M Medium Amplifier Power Tubes
Matched Duet (Medium Power Output Tube)
General Electric Design
The popular Groove Tubes GT-6L6-GED-M medium power tube duet (DM) is a faithful reproduction of the original General Electric "clear top" tube, one of the most popular tubes ever built. They are made in Groove Tube's Sylmar, California factory on the original General Electric machines, using original tooling, dies, materials, and process controls, as acquired from the liquidation of the last American tube factory in Ownesboro, Kentucky.
The GT-6L6-GE tubes uses the original General Electric plate material, a complex multi-layer alloy; and grids are made on the same grid winders used by GE. Some of the other components are made by the same manufacturers who made them for GE and the majority of the tube industry. Groove Tubes realized they would need a larger facility to do the final assembly, so they contracted to do some of the final assembly steps with their partner factory in China. This allowed them to maintain the quality they wanted, and still keep the price reasonable.
The GT-6L6-GE tubes sound and performance are extremely close to the original GE tube, which was famous for its deep bottom, burly mid-range, and sparkling and clear highs. Their sound is reminiscent of Carl Perkins and other artists all the way through Jimi Hendix. Both played and recorded primarily through Fender amps which used these tubes. Demand for the GT-6L6-GE is soaring, simply they sound so good.
We offer the GT-6L6-GED-M in matched sets of two (duets). Matched tube sets dramatically improve sustain by eliminating phase cancellation ,which occurs when dissimilar tones coming from unmatched tubes are combined and cancel out certain frequencies. They also improved harmonic balance, meaning all the notes you play will have the same amplitude with no weak or dull spots in your tone. Your amp will give you longer life, since balanced tube sets reduce stress that occurs when a stronger tube has to work harder to make up for a weaker tube. Your output transformer will actually run cooler, because matched tube sets drive the output transformer evenly.
Amplifier tubes don't last forever. Why not plan ahead and get new tubes in advance? Matched Groove Tubes will make your amp sound better and last long, and you'll be happier knowing you've got great tubes. You could save your present tubes as backups.
