Vacuum Tubes

Miniature full wave rectifier.

Triode, Dual, HF

Duodecar type used as horizontal-deflection amplifier in color and black-and-white television receivers.

Miniature type used in combined vertical-deflection-oscillator and vertical-deflection-amplifier applications in black and white television receivers. Requires miniature 9-contact socket.

Medium-mu twin triode 9-pin miniature type, intended for applications where dependable performance under shock and vibration is paramount. The 5814A is a "premium" version of the 12AU7.

Premium directly heated heavy duty rectifier Diode. Re-issue of the most popular rectifier valve ever built by Mullard. Helps extend the life of the other valves in the amplifier by allowing them to heat up before plate voltage is applied.

• Low internal voltage drop & controlled heater warm up time
• Excellent choice for both Hifi and instrument amplification
• Replacement/upgrade for all 5AR4/GZ34 types

Ruggedized heater-cathode type double diode using the 9 pin miniature construction. It is suitable for use in half or full wave rectifier applications or as a voltage doubler.

Miniature tube containing a high-mu triode and a sharp-cutoff pentode. The triode section is intended for service as a sync separator and the pentode section as a video amplifier.

Metal, power-amplifier pentode primarily designed for use in the output stage of video amplifiers. The tube is capable of operating at high plate current levels and exhibits high transconductance and high power sensitivity.

Special quality double triode designed for use as A.F. and D.C. amplifier.

Variable mu pentode amplifier in the octal metal (glass) construction. It is suitable for use with AVC in RF and IF amplifiers and minimizes cross modulation.

Pentode amplifier designed for application in power output stages of receivers

In the ECC823, Section 1 of the tube (pins 6, 7, and 8) is the low gain 12AU7/ECC82 spec (gain factor 17) and Section 2 (pins 1, 2, and 3) is the high gain 12AX7/ECC83 spec (gain factor 100).

Semi-remote cut off pentode voltage amplifier in the octal metal construction. It features high transconductance with low grid-plate capacitance and a dual cathode connection to minimize effects of common cathode circuit coupling.

Heater-cathode type duplex-diode high-mu triode designed for use as a combined detector, audio-frequency amplifier and automatic-volume-control tube

Transmitting beam power amplifier.

Pentode intended for use as A.F. amplifier.

Electro-Harmonix 6BM8 triode pentode tube. Made in Russia.
Contains one preamp triode and one power pentode in a 9 pin miniature package.

Gas-filled ballast tube designed to maintain a relatively constant current over a specified operating range.

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. The JJ KT88 is an excellent choice for Hi-Fi stereo equipment as well as guitar amplifiers. It can be used in place of 6550 tubes.

This triode has a full 40 Watts of power. The robust build of the JJ 300B offers high reliability in a classy package. Each tube comes with a factory certification with sets dual matched for anode current and gain. The JJ 300B has a balanced and detailed sound with a wide frequency response.

Heater-cathode type high vacuum twin diode using the lock in construction. It is intended for power rectifier service in AC operated equipment or for use with storage battery and vibrator in automotive receivers or amplifiers.

Filamentary type sharp cut-off pentode voltage amplifier. It is designed for service in low-drain battery-operated receivers as an RF, IF, or AF amplifier.

Miniature triode designed for use as a grounded-grid radio-frequency amplifier, frequency converter, or oscillator at frequencies below approximately 300 megacycles.
