  • Riverstone Audio - Tested/Matched Pair (2 Tubes) 7-Pin GE JAN 5654W Fully-Tested Vacuum Tubes - Upgrade for 6AK5 / 6J1 / 6J1P / EF95 Audio Amplifier Tube - GE 5654W tubes - Platinum Grade Pair

    A very closely matched pair (2 tubes) of vintage US-manufactured GE JAN 5654W vacuum tubes. All tubes are Amplitrex TESTED and MATCHED. Both plate current and Gm are matched to within 3%. We subject these tubes to multiple test cycles and plate voltages to determine stability. In addition to ip, Gm, leakage/gas, noise and life testing, the matched tubes undergo a final audio sound check to make certain they are indeed audio quality. Tubes that show the slightest abnormality are rejected. With our high standards, less than 50% of the NOS 5654W tubes we test are considered for use in these special matched sets. 5654W tubes were originally designed as a low noise premium-grade substitute for 6AK5 and EF95 vacuum tubes. The "W" designation refers to ruggedized, military grade, tubes; better quality control and internal design changes to enhance reliability and minimize microphonics/noise. This great sounding vintage tube has found new life as a replacement for 7-pin 6J1, 6J1P (6ZH1P-EV), 6AK5 and EF95 tubes and are commonly used by audiophiles looking for improved sound quality. All tubes selected for our tested/matched pairs will have identical date codes and are guaranteed to test at NOS levels of 5000 micro-mho or higher and a plate current (ip) of 7.2 mA or higher.

  • Mojave Audio Large Diaphragm Tube Condenser Professional Microphone

    Exceptional attention to detail defines the Mojave line of microphones designed with quality US components. The MA-200 is a large diaphragm, vacuum tube condenser microphone with a fixed cardioid pattern. Born to a lineage of fine microphone designs by David Royer, the MA-200 gives warm, full-bodied reproductions of vocals and instruments, with none of the shrillness and high frequency distortion artifacts that are often encountered with modern condenser microphones. Utilizing hand-selected 3-micron capsules, high-quality Jensen audio transformers and military-grade JAN 5840 vacuum tubes, the MA-200 performs at a level reminiscent of some of the best loved classic condenser microphones. The MA-200 power supply can be set for 115V and 230V, 50 or 60 Hz, through an internal switch (100V is also available). Each MA-200 microphone, power supply and cable set is burned in for 24 hours, carefully tested and evaluated, then packaged in its protective case-within-a-case with professional shock mount included. Features: Hand-selected 3-micron capsule, Jensen audio transformer, Military grade JAN 5840 vacuum tube, Internal switchable power supply voltage, and Ultra clean signal path. Recommended applications: Use anywhere you would use an expensive, large diaphragm tube microphone such as ...

    A pair (2 tubes) of closely matched mil-spec 9-Pin GE JAN 5670W vacuum tubes. These platinum grade tubes have undergone detailed screening, testing and audio testing. The vintage NOS GE 5670W tubes were obtained from factory sealed boxes and are a low-noise replacement for 2C51 and other 5670 tubes. 5670W tubes are also often used as a replacement for 6N3 and 6N3P vacuum tubes (the glass envelope of the GE 5670W tube is approx. 5 mm shorter than 6N3 and 6N3P tubes). The "W" designation in the 5670W tube number refers to ruggedized, military grade tubes; better quality control and internal design changes to enhance reliability. We test/match all 5670W vacuum tubes using Amplitrex AT1000 tube testers. Testing is performed using auto-bias mode (plate voltage is fixed at 150 V and plate current at 8.2 mA); grid voltage is measured to determine deviation from expected NOS level. Vp versus ip curves are also examined to determine balance between tube sections and overall tube performance (Vp-ip curves are generated under fixed-bias mode). Additional quality checks include shorts/leakage, gas, noise and a life test. These vacuum tubes are well balanced between tube sections. All tubes in our matched tube sets are guaranteed to test at NOS (new old stock) levels. Tube boxes are clearly l...

  • iFi Audio Premium NOS 6992 Matched GE5670 Vacuum Tube Pair Replacements

    The 6922 tube/valve is one of the most famous 'dual triode' designs and is ubiquitous. It has and is still, used in many tube/valve audio products from CD players to headphone amplifiers. First introduced by Western Electric in 1946 with the WE396A, from the 1950s onwards (and for the next 30 years thereafter) General Electric (and several other tube/valve manufacturers) followed Western Electric with their own premium version of 6922. This range had controlled warm-up and tight specifications on grid-current, noise and microphony. The result, significantly smoother and more organic sound qualities. While the 9-pin design was used, the electrical pin outs changed. As such, the GE5670 was not a straight 'drop-in' substitute for the 6922. So the GE5670 remain unloved and unused until......2014 when iFi brought out the iTUBE tube buffer/pre-amplifier. From our research of the tube inventories around the globe, we found the GE5670 to be in supply and with surprisingly good sound. While the iTUBE was designed from day one with the GE5670 in mind, we found that customers really liked the GE5670 in the iTUBE but they wanted more...yet because of the different electrical pin configuration, the GE5670 was a no go. The iFi solution was to machine-fabricate a special ceramic adapter with a ...
