# Vacuum Tubes

The first electronic amplification of sound was done with Vacuum Tubes. We have pre-amp, power and rectifier vacuum tubes among other types in New Old Stock from the golden era of American & European manufacturing as well as current production tubes from today.

#### Solid State Replacements

Solid state replacements for vacuum tubes are great for use for hard to find or costly vacuum tubes and for reducing 'sag' in power supply applications.

Solid State Rectifier - Yellow Jackets® YJR, For 5AR4, 5U4, 5Y3
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. The tube rectifier can easily be swapped back in when sag is desired. This Yellow Jacket® is a solid state device and as such does not come with vacuum tubes.
• Converts most audio amplifiers which use a vacuum tube rectifier 5AR4/GZ34, 5U4 or 5Y3 to a solid state device.
• Safe for all common amplifiers and transformers.

All Yellow Jackets® have a one year warranty against manufacturer defects.
$14.95 Solid State Rectifier - For 5AR4, 5U4, 5Y3 Tubes Solid State Rectifier Direct plug-in replacement for 5AR4, 5U4 and 5Y3 rectifier vacuum tubes in amplifiers with center tapped secondary power transformer. Use when less 'sag' is desired in the power supply; just switch back to the tube rectifier when 'sag' is desired.$9.95
Vacuum Tube - 5V6GT, Tetrode, Beam Power
Beam power amplifier designed for service in the output stage of 600mA series heater operated TV receivers. It has high power sensitivity and high power output with comparatively low supply voltage.
$9.90 Vacuum Tube - 6A3, Triode, Power Amplifier Filament type triode power amplifier designed for service in the output stage of audio amplifiers where high output and low harmonic distortion are desired. Its ratings and characteristics are similar to those of the 2A3 and 6B4G.$59.90

Sovtek 6A3 power triode tube. Made in Russia.
Starting at $56.00 Vacuum Tube - 6AG7 / 6AK7, Pentode, Power 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.$7.90
Vacuum Tube - 6AQ5A / 6HG5, Tetrode, Beam Power
Miniature beam-power pentode designed for use in the audio-frequency power output stage of television and radio receivers. It may also be used as a triode-connected vertical deflection amplifier in television receivers.
$9.90 Vacuum Tube - 6AR5, Pentode, Power Pentode power amplifier using the miniature construction. It is intended for service in AC and storage battery operated receivers where moderate power sensitivity and power output is desired.$9.90
Vacuum Tube - 6B4G, Triode, Power Amplifier
Glass triode power amplifier tube designed particularly for service in the power output stages of storage battery operated or a-c receivers
$52.65 Vacuum Tube - 6B4G, Sovtek Sovtek 6B4G power triode tube. Made in Russia. Sovtek is proud to announce the release of the Sovtek 6B4G vacuum tube. Unlike traditional 6B4G's, which consist of dual triodes connected in parallel inside the tube's envelope, the Sovtek 6B4G utilizes a single triode design with a Directly Heated cathode element. This updated design eliminates differential resistance loading common to other 6B4G's, yielding a much more reliable tube. In addition, the Sovtek 6B4G has a lower inter-electrode capacitance, offering a wider frequency response with high sound detail. Starting at$59.95
