Originally: $138.87 Partially Out of Stock Vacuum Tube - 35B5, Tetrode, Beam Power Miniature beam power amplifier especially designed for use in the power output stage of a-c/d-c receivers. Its small size and high efficiency make the tube especially useful where space limitation prevent the use of larger types.$3.55
Vacuum Tube - 35C5, Tetrode, Beam Power
Miniature beam pentode primarily designed for use in the audio-frequency power output stage of radio receivers. Features include high power sensitivity and high efficiency at relatively low plate and screen voltages.
$15.90 Vacuum Tube - 35L6GT, Beam Power Amplifier Beam pentode primarily designed for use in the audio frequency power output stage of radio receivers. Features include high power sensitivity and high efficiency at relatively low plate and screen voltages.$8.90
Vacuum Tube - 47, Pentode, Power Amplifier, ST Glass
Filament type output power pentode.
$34.50 Vacuum Tube - 50C5, Beam Power Amplifier Miniature beam pentode primarily designed for use in the audio-frequency power-output stage of radio receivers. The tube features high power sensitivity and high efficiency at relatively low plate and screen voltages$24.90
Vacuum Tube - 50L6GT, Beam Power Amplifier
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.
$9.90 Vacuum Tube - 5881, JJ Electronics The JJ Electronic 5881 is very similar to the 6L6GC but with a plate dissipation of 23W rather than 30W. Another physical difference is the shorter bulb. These tubes have a soft and balanced response that sounds great in both guitar amps and hifi equipment. The JJ 5881 will work in any amp that uses 6L6 tubes. Starting at$19.50
Vacuum Tube - 5881 / 6L6WGC, Sovtek
The 5881 is a very reliable tube that is widely used in many current production tube amplifiers. It has a warm tone with good 'bite.' This modern version is able to tolerate higher voltages than its 5881 / 6L6 cousins. The Sovtek 5881 delivers a warm, round tone that "sweetens" any vintage or modern guitar amp design. Built to rigid military standards, the 5881 will tolerate higher voltages than any other 6L6. In fact, they're frequently used as replacements for the old 7027 model in vintage Ampegs. Extremely consistent from piece to piece.
Starting at $20.65 Vacuum Tube - 5881, Tung-Sol, Tetrode, Beam Power The 5881 is the electrical equivalent to types 6L6 and 6L6GC except that the plate and screen dissipation ratings have been increased approximately 20 percent.$149.90
Vacuum Tube - 5881, Tung-Sol Reissue
Russian made reissue of the original Tungsol.
The 5881 is the electrical equivalent to types 6L6 and 6L6G except that the plate and screen dissipation ratings have been increased approximately 20 percent. It embodies a complete mechanical redesign which results in greater resistance to shock and vibration.
Starting at $23.65 Vacuum Tube - 5881WXT, Sovtek The Sovtek 5881WXT is the same as the 5881 but with a full size base for easy installation in vintage amp designs. The Sovtek 5881 delivers a warm, round tone that "sweetens" any vintage or modern guitar amp design. Built to rigid military standards, the 5881 will tolerate higher voltages than any other 6L6. In fact, they're frequently used as replacements for the old 7027 model in vintage Ampegs. Extremely consistent from piece to piece. The Sovtek 5881 has a heater voltage of 6.3 volts at 0.88 amperes. Starting at$25.95
Vacuum Tube - 5881 / 6L6WGB, Tetrode, Beam Power
The 5881 is the electrical equivalent to types 6L6 and 6L6GC except that the plate and screen dissipation ratings have been increased approximately 20 percent.
$59.90 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 - 6146B / 8298A, Beam Power Amplifier
Tube having high efficiency and high power sensitivity for use in mobile and stationary equipment. It is rated as an af power amplifier and modulator, a linear rf power amplifier, and a Class C rf power amplifier and oscillator.
$44.90 Vacuum Tube - 6550, Electro-Harmonix 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. Starting at$44.50
Vacuum Tube - 6550, JJ Electronics
The JJ Electronic 6550 is a robust tube built in the rugged fashion that JJ is famous for. At 35 Watts, these tubes have a warm round tone with a thick and defined low end. The JJ 6550 is an excellent choice for bass heads, tube organs, and Hi-Fi amplifiers.
