Vacuum Tubes

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.

Transmitting beam power amplifier.

Single heater-cathode type diode intended for service as the damping diode in the horizontal-deflection circuit of color television receivers. The diffusion bonded cathode practically eliminates one of the major failure mechanisms in damping diodes

Remote cut-off amplifier pentode designed for use as a radio-frequency or intermediate-frequency amplifier in a-c, a-c/d-c and auto receivers.

The Tube Amp Doctor KT-66 is an incredible remake of the classic British tube. With its large glass envelope contoured by smooth curves tapering into a rounded brown base, the TAD KT-66 not only looks like the original, it performs like the original. This KT66 offers plenty of headroom for a thick full bodied sound with smooth yet articulate highs. The KT-66 is famously used in vintage British plexi amps and makes a great replacement for that style of amplifier and many others. The TAD KT66 is matched for both plate current and transconductance and passes all of the tests of the TAD Premium Selection process. The TAD KT-66 can be used in any KT-66 position as well as 6L6GC and 5881 amps that can supply the required 1.27A for the heater.

Beam pentode designed primarily for use in the audio output stage of a-c and storage-battery-operated equipment. It is capable of supplying high power output with high sensitivity, high efficiency, and low third and higher-order harmonic distortion.

Miniature, filamentary, sharp-cutoff pentode intended for radio frequency or intermediate frequency amplifier use in battery-operated receivers.

Filamentary type power output pentode in the miniature construction. It is characterized by economy of filament power and ability to perform well at low plate supply voltages such as encountered in portable equipment.

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.

Miniature beam-power amplifier designed primarily for use in the output stage of compact a-c/d-c receivers. The 50B5 features high power sensitivity and is capable of providing a relatively high power output

Sovtek 6SL7GT vacuum tube, made in Russia.

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

Russian Tung-Sol 6EU7 tube. High-Mu twin triode with 9 pin miniature base. Made in Russia.

Medium-mu triode using the lock-in construction. It is designed for use as an oscillator, detector, or amplifier. It is characterized by moderately high transconductance. It is particularly applicable for service in the higher frequencies.

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).

Filament type power-amplifier pentode designed for use in the output stage of low drain battery operated equipment. The 1A5GT may be operated singly or in push-pull combination.

Beam pentode designed for use in the audio-frequency power output stage of radio and television receivers. Features include high power sensitivity and high efficiency at relatively low plate and screen voltages.

Miniature power amplifier pentode designed for use in the power output stage of compact, battery operated equipment. It is particularly useful in three-way portable receivers which employ 90-volta batteries.

Duplex-diode high-mu triode intended primarily for use as a combined detector, amplifier, and automatic-volume-control tube in radio receivers. The triode section incorporates a high amplification factor

Beam-power pentode designed for use in the audio frequency power output stage of television and radio receivers. Capable of supply high power output with high sensitivity, high efficiency, and low third and higher-order harmonic distortion.

Tung Sol 7591A beam-power tube. Made in Russia.

9-pin miniature type high-mu twin triode, with heater having controlled warm-up time.

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.

Electro-Harmonix 6CA7 Vacuum Tube Big bottle beam-tetrode version of EL34. Perfect EL34 replacement for Musicman amplifiers.
