Vacuum Tubes

The Tube Amp Doctor 7025 / E83CC Highgrade is the premium selection of the RT003 ECC83-Cz for V1 positions. This tube works exceptionally well in the V1 position of high gain amps, combo amps, and phono/audio-amps. The Tube Amp Doctor 7025 / E83CC Highgrade is a miniature, high-mu twin triode with good gain, round deep bass, somewhat compressed mids and very smooth top end. Selected and recommended for guitar amps to smoothen up the tone or for HiFi to shape the body of sound more to “that” tube tone. Best for jazzy and thick clean as well as for vintage bass response. The TAD™ 7025 / E83CC Highgrade can replace any 7025, 12AX7WA, 12AX7WB, 12AX7LPS, 12AX7EH, ECC83 or E83CC.

Isa full-wave high-vacuum rectifier designed for damper service in television deflection circuits. It can also be used in conventional rectifier applications.

Totally Tweed! The preferred OEM tube of '50s-era Fender Tweed Champ and Deluxe amplifiers The Tungsol 6V6 has a geometry designed to safely handle the higher voltages used in guitar amps " plus heavier plate and grid materials. The result.. better mids and bottom while keeping the smooth top of the classic 6V6's. The Tungsol 6V6 breaks up evenly from low E to high up the neck. Blues players will LOVE these tubes for the way they sing!

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.

Mixer tube designed for service with a separate oscillator as the first detector in superheterodyne receivers. The control grid is of the remote cut-off type which allows the use of AVC and minimizes cross-modulation.

Miniature pentode intended for use as a radio-frequency or intermediate frequency amplifier in automobile radio receivers. The tube is specially designed to operate with plate and screen voltages supplied directly from a 12-volt storage battery.

Rugged full-wave filamentary type rectifier designed for use in applications requiring resistance to shock or vibration.

High vacuum full wave rectifying tube.

Miniature, four-electrode, inert-gas-filled thyratron with negative control characteristics of the tube include a high control ratio essentially independent of temperature over a wide range low grid-anode capacitance and very low grid current.

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 Tube Amp Doctor EF86 / 6267 is a low noise and low microphonic version of the vintage pentode. These tubes were famously used in classic HiFi equipment and microphone preamps. The original Vox® AC15 circuit also used an EF86 and now, thanks to its recent availability, there are plenty of options for guitar amplifiers utilizing this unique tube. The TAD EF86 / 6267 meets all of the standards of the Tube Amp Doctor Premium Selection process. This tube has a rugged construction featuring an aesthetically pleasing perforated shield. The TAD EF86 / 6267 will work in and EF86 or 6267 position.

Small, sturdy, beam power amplifier tube intended for pulse modulator service in both fixed and mobile equipment.

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.

Compactron dissimilar double triode designed for used as a combined vertical-deflection oscillator and amplifier in television receivers.

Premium high-voltage power pentode. An extremely faithful reissue of the XF2 Mullard EL34 from the 1960s.

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

Heater-cathode type pentode amplifier tube with remote cut-off characteristics and is designed for use as a radio frequency or intermediate frequency amplifier in a-c or battery operated equipment

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.

Superior high-power Octal Beam Tetrode, suitable for any amp using 6550 or KT88. Designed to hold up in even the most punishing environment of high powered bass amps, such as Ampeg SVT. With 42 watts of plate dissipation in tetrode operation and 44 watts in triode, power is improved even over desirable vintage types.

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.

Beam power tube with a separate grid - no. 3 base-pin terminal for "snivets" control. The tube is designed for horizontal-deflection-amplifier service in black-and-white TV receivers.

The JJ Electronic 5Y3S is a ruggedly built octal rectifier tube with a directly heated cathode. This tube’s solid construction and thick glass envelope offer high reliability. The JJ 5Y3S will work in any 5Y3 position.

Heater-cathode type diode designed for use as a half-wave rectifier in ac/dc receivers. A heater tap is provided to permit operation with a panel lamp.

Special quality pentode designed for use as a wide band output tube.
