Miniature, high mu triode, double diode intended for application in color and monochrome television receivers. Separate cathode connections for each section and controlled heater warm-up time to insure dependable operation in series string receivers

Twin-diode with individual cathodes brought out to separate base pins. The 6H6 is designed for service as a diode detector, automatic volume control rectifier, or as a low current power rectifier

This 6V6 has the standard rugged construction we’ve come to expect from JJ which allows it handle much higher plate voltages than the typical 6V6 tube. The JJ 6V6 can even be used in place of a 6L6 in some amplifiers. Overall this tube has a warm and balanced tone with incredible separation and response. These tubes can cover a spectrum of sounds and styles all within the same amplifier.

The JJ Electronic 6L6GC is the classic pentode built with the rugged construction that only JJ could deliver. At 30W, this tube delivers plenty of headroom. The highs are clear and responsive with warm mids and tight solid lows. Known for their reliability and articulation, the JJ 6L6GC is a great option guitar amplifiers and Hi-Fi stereo equipment.

Another classic from JJ. This tube features a rugged construction leading to an incredibly reliable EL34 with astonishing tone. Overall the sound is nicely balanced with tight lows, a rich and dynamic mid range and clear highs. The JJ EL34 is a great replacement for guitar amplifiers and stereo amps as well.

The JJ Electronic EL84 is a solidly built EL84 / 6BQ5 with excellent tonal qualities. JJ’s rugged construction of this tube offers high reliability without any compromise to the sound. This tube has solid lows with warm bright mids and shimmery highs. When saturated the harmonics are rich and dynamic. The JJ EL84 nails the classic sound of this tube. This tube can replace any EL84 or 6BQ5 tube.

Russian made reissue of the original Tungsol. The Ultimate 12AX7. Big, warm, and musical. High Gain, ultra-low microphonics, and superb linearity with a dynamic 3-D sound. Available with gold pins.

The JJ Electronic GZ34 / 5AR4 is rugged rectifier at a reasonable price. JJ has a reputation for building sturdy tubes and this one is no exception. Users report that the JJ GZ34 / 5AR4 is a reliable rectifier in their Vox, Fender, and hifi amplifiers.

This Russian tube is full bodied and bright with a more straightforward presentation. It packs a lot of bite with its higher-than-normal gain. In overdrive, it offers a lot of crunchy fizz. High gain preamplifier tube with ultra low noise and detailed, musical tone. Unique spiral filament eliminates filament to cathode induced hum common on amplifiers that use AC on the filaments.

This tube has a well balanced, colorful tone with strongly defined lows, mids and smooth highs. It allows for more clean head-room than higher gain 12AX7s. In overdrive, it is smooth and strong with well defined lows and mids. When pushed into overdrive it offers clean distortion with well balanced lows and mids. The JJ 12AX7 is well suited for all types of music and playing styles. It is also highly recommended for studio pre-amps and hi-fi gear

The JJ Electronic E34L adds more power to a standard EL34 due to its higher grid voltage rating. This increase gives the tube more headroom and a tighter response on the low end. The wide frequency response of this tube offers excellent harmonics that work in a variety of genres ranging from the cleanest cleans to rich and aggressive breakup.

The JJ Electronic 5Y3S is a ruggedly built octal rectifier tube with a directly heated cathode. This tube’s solid construction and thick glass envelope offer high reliability. The JJ 5Y3S will work in any 5Y3 position.
