Triode, Dual, HF

The 12AT7 is a miniature, high-mu, twin triode designed for use as a grounded-grid radio-frequency amplifier or as a combined oscillator and mixer at frequencies below approximately 300 megacycles.

Medium-mu twin triode intended for service in radio and television receivers or in audio amplifiers. The tube is suitable for use in a variety of stages, such as general-purpose amplifier, phase inverter, oscillator, or multivibrator.

Combines a high mu triode and two independent diode units in the 7-pin miniature construction. It permits a single tube to function as detector, AVC rectifier, and audio amplifier.

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.

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 medium-mu twin triode designed primarily for use in low-level stages of high-gain audio-frequency amplifiers. The tube is specially designed to exhibit low noise and low microphonic output.

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

Miniature low-mu triode designed primarily for service as a vertical-deflection amplifier in television receivers. The tube features high plate current at relatively low plate voltages

Miniature, medium-mu twin triode designed primarily for use as a vertical-deflection amplifier in television receivers. The two sections may be employed in parallel, or as a combined vertical-deflection amplifier and vertical oscillator.

The YJR is a direct plug-in replacement adapter for use in most amplifiers that use 5AR4/GZ34, 5U4, 5Y3 or similar full-wave rectifier tubes. The YJR converts your amp's vacuum tube rectifier to a solid state rectifier, reducing tube sag for a tighter sound and feel.

0A2 or 150C2 - Voltage Regulator, Diode, miniature glow-discharge type.

Voltage Regulator, Diode, Glow-Discharge type.

The 0B2 is a two-electrode, inert-gas-filled cold cathode miniature tube intended for use as a voltage regulator.

Beam power tube of the 9-pin miniature type designed for use as the output amplifier in automobile radio receivers operating from a 12-volt storage battery. The 12AB5 can provide high power output.

Electro-Harmonix 12AT7 / ECC81 Vacuum Tube Large plate format, superior dissipation over the originals. Perfect for reverb and driver circuits.

A good choice for phase inverters, reverb drivers, and general preamp use. This tube offers low noise, low microphonics, and warm smooth tones at a great price. Like all JJ tubes, it has a rugged construction that doesn’t compromise the sound of your amp. The JJ 12AT7 is a solid replacement for any 12AT7, ECC81, or 6201 tube. It can also be used to replace 12AX7 tubes in position 1 to reduce gain.

The 12AU6 is a pentode amplifier having a sharp cut-off control characteristic using the miniature construction. With high transconductance, low grid-plate capacitance, it is intended for service as either an RF or AF amplifier.
