Vacuum Tubes

Miniature diode sharp-cutoff pentode designed for use as a combined detector, audio-frequency amplifier, and automatic-volume-control tube in compact, battery-operated receivers.

Frame grid double triode of miniature construction with high transconductance and low noise, designed for service in television receiver VHF cascode RF amplifiers, IF amplifiers, and phase inverter stages.

Compactron containing two medium-mu triodes and one high-mu triode.

A different construction of the classic EL34 tube that offers a different tonal palette than the original. This tube has a more compact plate structure than standard EL34’s. The JJ EL34 II has an increased low to low-mid end with plenty of headroom to spare. The JJ EL34 II is stronger than the original but not harsh sounding in any way.

The Perfect Choice for Stereo Audio Applications - Ideal as a Balanced Driver. Latest revision providing great musical performance and rich tone. This TAD 12AU7A / ECC82 has especially strong systems which are selected to provide two symmetric triodes. The perfect choice for stereo audio applications and ideal as a balanced driver.

Tung Sol 5751 dual triode preamp tube. Made in Russia. NOS specs call the 5751 a “special 12AX7” having a high-mu amplification factor of 70.

Miniature beam-power pentode for use as an audio-frequency power amplifier. In this application the tube is capable of delivering an output of approximately 4.5 watts.

Miniature pentode designed for use as a radio-frequency or intermediate-frequency amplifier in television receivers. Features of the tube include high transconductance and low interelectrode capacitances.

Miniature, high-mu, twin triode primarily designed for use in low-level stages of high-gain audio frequency amplifiers.

Tung Sol 6SL7 dual triode preamp tube. Made in Russia. The best current production 6SL7 available. NOS performance and sound at a fraction of the price. Sweeten up the preamp section of that Vintage Ampeg B-15.

Blue glass envelope. A sonically faithful reproduction of the original tubes with a robust construction encased in a thick glass envelope. The JJ KT88 delivers a powerful 42 Watts with plenty of headroom to spare. This tube has a tone that is warm and lively with a detailed and balance response.

Heater-cathode type of tube intended for use in compact, light-weight equipment. Because of its small size, the 6AK6 can be used singly or in push-pull to effect a more compact design of power-line receivers.

The 6CW4 isa high-mu triode for use as a grounded-cathode, neutralized RF-amplifier tube in tuners of VHF television and FM receivers.

Pentode amplifier designed for application in power output stages of 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

Heater-cathode type power rectifier in the miniature construction. Its low voltage drop and small size adapt it to use with vibrator-type inverters in automobile receivers.

The type 3Q4 is a miniature type power-amplifier pentode designed for use in the output stage of battery operated equipment.

Compactron beam-power pentode designed for use in the horizontal deflection amplifier in television receivers. A separate connection is provided for the beam plates to minimize "snivets".

Metal pentagrid converter. It is intended to perform the combined functions of the mixer and oscillator in superheterodyne receivers, especially those of the all-wave type. The 6SA7 is constructed to provide excellent frequency stability.

Duplex-diode high-mu triode designed for use as a combined detector, automatic-volume-control rectifier and audio amplifier in a-c, a-c/d-c, or automobile receivers.

The JJ Electronic EL509S is an eight pin octal based version of the EL509 / EL519. This modified version does not have the top plate cap which is instead wired to a pin on the octal base. This tube is rated for 700V and 42 Watts plate dissipation. The JJ EL509 is popularly used in output transformerless OTL amplifiers.

The 6EJ7 is a high transconductance sharp-cutoff pentode in the 9 pin miniature construction.

A sonically faithful reproduction of the original tubes with a robust construction encased in a thick glass envelope. The JJ KT66 delivers a powerful 25 Watts with plenty of headroom. This tube has a tone that is warm, thick, and straightforward. With a more balanced sound than the 6L6GC, the JJ KT66 is an excellent choice for a full bodied tone.

The 0D3-A is a two-element gas filled, cold cathode voltage regulator. It is designed to provide a regulated output of approximately 150 volts.
