Groove Tube Gold Series GT-12AX7-C Preamp Tube The ever-popular and sorely missed Chinese 12AX7 is finally back! This tube has a warm, fat, old-style tone favored by blues players and the classic rock crowd. Fender GT12AX7A Tube Groove Tubes have improved harmonic balance, longer life, matched gain to frequency response ratios and require no rebiasing when replaced in color-coded sets. Fender 12AT7 Single Amp Tube Fender Tubes are back! Same high quality, same great price! Fender hand-selects these 12AT7 single amp tubes for premium-quality tone and long life. Premium tone. Long life. Great price. Groove Tube Gold Series GT-EL84-S Matched Power Tubes Low (1-3 GT Rating) This GT-EL84-S Matched Power Tube Duet and Quartet features a new European version with even more response, higher power, and warmer tone. It's the low-power pentode popularized in the early Vox AC30 amps. It was rediscovered by Matchless and now is used by nearly every tube amp company. It has a quick, soft overdrive distortion—great for recording but usually too low volume for live gigs. Ruby Tubes 6L6GC STR Matched Amp Tubes Quartet A Santana favorite with full, clear tone! All Ruby output tubes are labeled on the base with the exact matching measurements for plate current and transconductance. By matching these parameters, optimal performance and long life are ensured. Comes with a 6-month replacement warranty. ******** Labeled with matching measurements for plate current and transconductance. Optimal performance and long life. 6-month replacement warranty. Fender GT6L6 Tube Boost your guitar amp's tone with quality replacement tubes. Groove Tubes have improved harmonic balance, longer life, matched gain to frequency response ratios and require no rebiasing when replaced in color-coded sets. Red-clean; blue-dirty; white-medium Boost your guitar amp's tone with quality replacement tubes. Tungsol 6L6 GC STR Power Tube Sets Built to the same special tube request specs of leading amp manufacturers of the 1960s, this rugged and reliable power tube excels in the most demanding guitar amp circuits. Soft, medium, and hard style descriptions refer to break up modes of the tube for an overdriven guitar signal. The Tungsol 6L6 GC STR Power Tubes are soft-rated tubes that break up slow and have the highest amount of headroom, while hard-rated tubes break up easier and have the least headroom, yielding a heavier, harder distortion. Medium-rated tubes fall in between. Svetlana EL34 Tube The Svetlana EL34 Tube is a great replacement for Marshall and Dynaco ST-70 amplifierss. Refresh your amp with these pro-approved tubes. Mullard EL34 Tube The Mullard EL34 is a reissue of the Classic EL34 Mullard tube. The timeless sound is back! Groove Tube Gold Series GT-6550-C Matched Power Tubes GT-6550-C Duet A softer version of the older USA 6550A, with a nice distortion character. This tube has a distortion that is between a 6L6GC and a 6550A. In older Marshall's that have 6550's, this tube will give you more compression and distortion at lower levels than the other 6550 offerings. This tube is terrific in Class A amps such as the GT Solo Single when you want to have a lot of output for smaller live venues. Many people prefer these in some Marshall amps where more clean headroom and output is desired. Groove Tube SAG-MHG Marshall High Gain Preamp Retube Kit SAG-MHG Marshall High Gain Kit Marshall High Gain kit, 2 SAG ECC83S and 1 AX7-MPI tubes optimized for the preamp stage of Marshall style amps. Specially selected from premium Groove Tubes preamp tubes which have been tested to meet the GT standard. Special Applications Group (SAG) provides further testing and grading for certain performance characteristics. This three tube set is optimized for your Marshall, Bogner, Rivera, Mesa or British type amps which use (or will benefit from) the ECC83 (12AX7) preamp tubes. SAG-MHG includes two high output preamp tubes to be used in the V1 and V2 positions, and one MPI (matched phase inverter) tube for the V3 position. The matched phase inverter may be a 12AX7 or an ECC83, as it will be matched for it's response curves with the other two tubes. The phase inverter is not part of the tine generation stage, it is a current driver. The V1 and V2 tubes will increase the front end output structure of amplifiers from about 10% to as much as 25% or more over typical stock tubes. The V3, matched phase inverter tube will assure a balanced output section when used with matched power tubes (highly recommended) which will assure sustain across the entire range of your instrument. The MPI (Matched Phase Inverter) is a SAG selected 12AX7 or ECC83, as this tube is not part of the tone generation stage, but part of the output section and is chosen for its current drive and rise time characteristics. Use this MPI in any application where a phase inverter / driver of the ECC83/12AX7/7025 tube is specified. The phase inverter / driver position of a guitar or bass amp is a current driving position, and not part of the tone generation stage. These tubes are selected for specific characteristics, so may be a 12AX7R, 12AX7C, 12AX7M or another 12AX7 type that has been selected for specific curve traces as the objective. This tube cannot be specified as to type in the kit. These kits also work particularly well in Fender Blackface and Silverface amps where the increased gain and current out of the first gain stage combined with a switch from the 12AT7 in the phase inverter to a 12AX7 will yield a much more aggressive tone. These amps which are normally considered to be on the "clean" side will become more aggressive with this kit. Fender GT6V6 Tube Groove Tubes have improved harmonic balance, longer life, matched gain to frequency response ratios and require no rebiasing when replaced in color-coded sets. THD Triode Yellow Jacket for Cathode Biased Amps Converts your amp to Class A EL84 operation. The YJC is an adapter that permits the use of an EL84 power tube in place of a 6L6, EL34, or 6550 in cathode-biased amps. There are no adjustments to make and no modifications are necessary. You simply plug the Yellow Jacket into the amp's output tube sockets, plug the provided EL84s into the Yellow Jacket, turn on the amp, and play. THD's Yellow Jacket converters not only rearrange the pin locations of the tubes, but also provide the necessary current limiting on the screens and cathode as well as blocking the amplifier's grid-bias voltage, configuring the EL84 in a Class-A, self-adjusting cathode-bias circuit. When the Yellow Jacket Converters are installed in larger amplifiers intended for 6L6s or EL34 output tubes, the high plate and screen voltages are reduced as well as current limited to protect the EL84 and to drop output power. When a pair of Yellow Jacket are used in a Marshall 50W or similar amplifier, the overall power drops to about 20W and takes on more of the character of an old Vox AC30. The distortion is smoother and more even and the output is both substantially reduced and more compressed due to the Class-A nature of the Yellow Jackets. In a 100W amp like a Twin Reverb or Marshall 100, either 2 or 4 Yellow Jackets can be used. If only 2 are used and the other 2 sockets are left empty, the output is dropped to about 20 watts. With 4 in place, the amp puts out about 40W and takes on a whole new warmth and richness. Will they hurt your amp? No! Yellow Jacket converters are safe for all amplifiers and transformers. As all Yellow Jacket converters internally regulates voltage and current they put no extra strain on amplifiers' power and output transformers or internal components. Using the Yellow Jacket in higher powered amplifiers actually reduces the strain on the transformers and internal components because it reduces the overall wattage of the system. Furthermore, the heater (or filament) current of the EL84 is lower than that of the 6L6, EL34 or 7591, so the Yellow Jacket will reduce the strain on the filament windings of the power transformer as well. Use an EL84 in place of a 6L6, EL34, or 6550 in cathode-bias amps. THD Triode Yellow Jacket for 6V6 Amps Use an EL84 in your 6V6 amp. Tubes included. Electro-Harmonix 6V6EH Tubes Great for Fenders! 6V6EH Tubes produce sweet, singing tone for high plate voltage amps like the Fender Deluxe Reverb. Fender 6550A Precision Matched Power Amp Tubes Matched for reliability and tone.
