Vacuum Tubes

Compactron beam-power pentode designed for use as the horizontal deflection amplifier in television receivers.

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.

Heater, for unipotential cathode. 117 volts AC-DC.

Combines two low-mu triodes in the lock-in construction. It is designed for use either as a phase inverter or as a voltage amplifier.

Sharp-cutoff pentode designed for use as a radio-frequency, intermediate frequency, or audio-frequency amplifier in battery operated receivers.

Miniature medium-mu twin triode suitable for a wide variety of general-purpose amplifier, oscillator, and multivibrator applications.

Miniature types used as RF or IF amplifiers especially in high-frequency wide-band applications at frequencies up to 400MHz.

Electro-Harmonix 6CG7 dual triode preamp tube. Made in Russia.

High-slope R.F. pentode particularly suitable for use in F.M. receivers.

The TAD KT88-STR Redbase® is built in the style of the early British MOV KT88 with the big and heavy glass envelope and beautifully polished metal base. The Redbase® features a gold control grid for outstanding performance and reliable stability. A breath-takingly big and precise tone and great appearance make the new TAD KT88-STR Redbase® the best choice for both, high-end audio applications and powerful bass guitar amps, providing a natural and three dimensional tone with pleasingly full warmth and fine, subtle highs. A very musical response, with great sound and finest details in mids and top-end; a linear and harmonious overall response with a very organic tone, make the TAD KT88-STR Redbase® TAD’s favorite tube in the KT88 and 6550A class.

Genalex Gold Lion ECC81/B739 (12AT7) dual triode preamp tube with gold pins. Made in Russia. Original Genalex Gold Lion ECC81/B739 tubes are considered the best 12AT7 types ever made. They are also among the rarest types available. They exhibit a large detailed soundstage that is characterized by an expressive midrange, deep tight bass, and a smooth extended high end. The reissue Genalex Gold Lion ECC81/B739 recreates the sound signature of the original. This tube features balanced sections and gold plated pins.

Heater-cathode type beam tube of miniature construction designed primarily to form the combined operations of the limiter, discriminator, and audio-voltage amplifier in FM and intercarrier television receivers.

Sovtek 6H30PI dual triode preamp tube with gold pins. Made in Russia. The 6H30 is a medium-mu dual triode with a very high-perveance cathode. The low plate resistance, combined with a superior linearity, and a true 4 watt per plate dissipation, make for a high performance voltage amp or driver.

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 0C3-A is a two-element gas filled, cold cathode voltage regulator. It is designed to provide a regulated output of approximately 105 volts.

Miniature space-charge-grid tetrode intended for use as a driver for the transistor power-output stage of automobile radio receivers.

Low-voltage, low-current drain, battery type power pentode. It is designed for service with 90 volts of "B" battery and a single dry cell "A" battery.

Low-voltage, low-current drain, battery type triode. It is designed for service as an oscillator, detector, or amplifier in receivers using 90 volts "B" battery and a single dry cell "A" battery.

High vacuum rectifier intended for use in full-wave applications. The tube incorporates an indirectly heated cathode which is internally connected to the heater

Miniature sharp-cutoff pentode. Its high transconductance and low input and output capacitance adapt it to use as a wide-band amplifier or as a reactance tube.

Compactron, containing three high-mu triodes with separate pin connections for all three cathodes, grids, and plates. It is especially designed for use as an oscillator-mixer, grounded-grid amplifier, and automatic frequency control service.

Double triode with dissimilar section in the 9 pin miniature construction. Section #1 has a high mu and is intended for use as a vertical deflection oscillator. Section #2 has a low mu and is designed for use as a vertical deflection amplifier

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

Heater-cathode type beam power amplifier tube designed for service in the output stage of a-c or battery-operated equipment.
