Vacuum Tubes

Miniature half-wave rectifier for use in line-operated equipment having series-connected heaters. The heater is tapped to permit operation of a panel lamp.

Metal sharp-cutoff pentode designed for use as a biased detector or high-gain amplifier.

Miniature remote-cutoff pentode designed for use as a radio-frequency or intermediate frequency amplifier in compact, battery-operated equipment.

Miniature remote-cutoff pentode intended for use as a high-gain radio frequency or intermediate-frequency amplifier. Its remote-cutoff characteristic makes it suitable for use in circuits to which it is desired to apply automatic-gain-control.

Mullard 12AT7 / ECC81 dual triode preamp tube. Made in Russia.

Miniature sharp-cutoff pentode designed primarily for use as a high gain radio-frequency or intermediate-frequency amplifier. Low grid-plate capacitance and high transconductance make it especially suited for high-frequency wide-band applications.

Miniature tube which contains two dissimilar triodes in one envelope. The tube is intended for use as a combined vertical deflection oscillator and amplifier in television receivers.

Beam power pentode primarily designed for use as the horizontal-deflection amplifier in television receivers.

High frequency twin triode preamplifier tube used in studio and hi-fi equipment.

Octal rectifier tube (Max DC output current = 125 mA) An indirectly heated diode intended for rectification of commercial-frequency alternating current. It has a 140 mA maximum output and filament voltage of 5 V and a filament current of 2 A ± 0.2 mA.

Miniature, medium-mu, semi-remote cutoff twin triode intended for application as a VHF cascode amplifier in a television receiver.

The JJ Electronic 7027A offers the same reliability and tone as the JJ 6L6GC but with the correct pinout for vintage amplifiers that use 7027 tubes like older Ampegs. At 30W, this tube delivers plenty of headroom. The highs are clear and responsive with warm mids and tight solid lows. Known for their reliability and articulation, the JJ 7027A is a great option guitar amplifiers and Hi-Fi stereo equipment.

Medium-mu twin triode suitable for use in a wide variety of general purpose amplifier and phase-inverter applications. Except for heater characteristics and ratings, the 12SN7GA-B is identical to the 6SN7GTB

Superior power Beam tetrode with large plate dimensions and improved grid structure for increased power handling capabilities. Excellent tone and performance compared to most other 6L6 or KT66 types.

Miniature heptode primarily designed to perform the combined functions of the mixer and oscillator in superheterodyne circuits in both the standard broadcast and FM bands.

The 50L6GT is designed for service in the output stage of ac/dc receivers. It delivers a high power output with high power sensitivity from low supply voltages.

Miniature twin-triode primarily designed for service in computer applications. Each triode section features a high zero-bias plate current, a sharp-cutoff characteristic, and a separate cathode connection.

Miniature medium-mu twin triode suitable for use in a wide variety of general-purpose applications. It is particularly useful as a vertical-deflection oscillator and horizontal-deflection oscillator in television receivers.

The Sovtek 6550WE was designed to be the finest 6550 ever produced. Thicker plates, improved heat dissipation, higher transconductance, and increased linearity are just some of the inherent aspects of the new Sovtek super 6550s. The resulting performance advantages include 5% higher output power, increased reliability, greater headroom, and superior tone. The 6550WE features a metal-ringed base for increased power-handling capabilities.

Miniature, medium-mu twin triode for use as a frequency divider in computer applications.

Dissimilar double triode in the 9-pin miniature construction. It is especially suitable for applications requiring a high gain voltage amplifier and a cathodyne type phase-inverter.

Miniature full-wave high-vacuum rectifier intended for use in power supplies which have low d-c output-current requirements.

Tung Sol 12AU7W / 6189 dual triode preamp tube. Made in Russia.

The 6K6GT is an indirectly heated cathode type power amplifier pentode designed for service in the output stages of AC, AC/DC and storage battery operated receivers.
