Vacuum Tubes
The first electronic amplification of sound was done with Vacuum Tubes. We have pre-amp, power and rectifier vacuum tubes among other types in New Old Stock from the golden era of American & European manufacturing as well as current production tubes from today.

Electro-Harmonix 12AT7 / ECC81 Vacuum Tube Large plate format, superior dissipation over the originals. Perfect for reverb and driver circuits.
$12.95

9 pin miniature preamp tube (Amplification Factor = 60)
Durable phase splitter or driver tube. Excellent in vibrato or reverb circuits where consistent, high output power is desired.
Durable phase splitter or driver tube. Excellent in vibrato or reverb circuits where consistent, high output power is desired.
$19.95

A good choice for phase inverters, reverb drivers, and general preamp use. This tube offers low noise, low microphonics, and warm smooth tones at a great price. Like all JJ tubes, it has a rugged construction that doesn’t compromise the sound of your amp. The JJ 12AT7 is a solid replacement for any 12AT7, ECC81, or 6201 tube. It can also be used to replace 12AX7 tubes in position 1 to reduce gain.
Starting at $10.95

The 12AT7 is a miniature, high-mu, twin triode designed for use as a grounded-grid radio-frequency amplifier or as a combined oscillator and mixer at frequencies below approximately 300 megacycles.
$14.90

The 12AU6 is a pentode amplifier having a sharp cut-off control characteristic using the miniature construction. With high transconductance, low grid-plate capacitance, it is intended for service as either an RF or AF amplifier.
$5.90

A medium gain dual triode built with the quality and reliability that we’ve come to expect from a JJ tube. This 12AU7 offers smooth tones and clear definition which is why it’s no surprise that this tube is often found in hifi equipment as well as guitar amplifiers.
Starting at $10.95

Superior medium-Mu Twin Triode for use in preamplifier and driver circuits. Standard replacement for all circuits requiring 12AU7/ECC82 types.

Medium-mu twin triode intended for service in radio and television receivers or in audio amplifiers. The tube is suitable for use in a variety of stages, such as general-purpose amplifier, phase inverter, oscillator, or multivibrator.
$22.90

Combines a high mu triode and two independent diode units in the 7-pin miniature construction. It permits a single tube to function as detector, AVC rectifier, and audio amplifier.
$5.90

Miniature, medium-mu twin triode for use as a radio-frequency amplifier or as a combined oscillator and mixer in VHF television receivers. It my also be used as an audio-frequency amplifier.
$6.90

Miniature high-mu twin triode each section of which has an individual cathode connection - especially suited for use in resistance-coupled voltage amplifiers, phase inverters, multivibrators, and industrial-control circuits.
$59.95

Russian-made Mullard Reissue 12AX7 dual triode. Large sound stage with excellent detail. Factory selected for low noise and microphonics. Great for hi-fi amps.
$18.95

9 pin miniature preamp tube (Amplification Factor =100). Very good gain, tight deep bass, fat mids and silky top end with overall definition and brightness. Selected with balanced systems and recommended for guitar amps to improve overall response.
$19.35

The JJ Electronic 12AX7 / ECC83 has quickly become a modern classic in preamp tubes. Its rugged design and rich harmonics make this tube an obvious choice for musicians who need a reliable and high quality tube at a reasonable price. The balanced tone of the JJ 12AX7 works well in any amp.
Starting at $10.95

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.
Starting at $15.95

RCA brand. Miniature high-mu twin triode each section of which has an individual cathode connection - especially suited for use in resistance-coupled voltage amplifiers, phase inverters, multivibrators, and industrial-control circuits.

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.
Starting at $13.25

9 pin miniature preamp tube (Amplification Factor = 100). This Russian tube is full bodied and well balanced. It has a high gain with a very smooth presentation. In overdrive, it is not quite as defined as the 12AX7-S-JJ, but it offers more crunchy fizz.
