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.
T-KT66-JJ Vacuum Tube - KT66, JJ Electronics
A sonically faithful reproduction of the original tubes with a robust construction encased in a thick glass envelope. The JJ KT66 delivers a powerful 25 Watts with plenty of headroom. This tube has a tone that is warm, thick, and straightforward. With a more balanced sound than the 6L6GC, the JJ KT66 is an excellent choice for a full bodied tone.

T-6J7_EF36 Vacuum Tube - 6J7 / EF36, Pentode, Sharp Cut-Off
Sharp cut-off general purpose amplifier. With the exception of heater and capacitance ratings, the electrical characteristics are similar to those of the 6C6.
T-EL34-SV-X Vacuum Tube - EL34, Svetlana
Superior power beam tetrode, engineered for demanding high fidelity, reliability and overall warmth. Traditional brown base.
Starting at $25.95
T-EL844-JJ Vacuum Tube - EL844, JJ Electronics
The JJ Electronic EL844 is a variation on the classic tube which reduces the overall headroom by 25%. With the reduced power, hitting that rich distortion that the EL84 is notorious for is more manageable. This tube will hit full saturated power tube sounds without having to crank the amps volume as high which makes them a great choice for recording as well as home / bedroom use.
Starting at $13.95
T-6BN8 Vacuum Tube - 6BN8, Dual Diode, Triode
Miniature, high mu triode, double diode intended for application in color and monochrome television receivers. Separate cathode connections for each section and controlled heater warm-up time to insure dependable operation in series string receivers

Starting at $33.95
T-12X4 Vacuum Tube - 12X4, Rectifier, Full Wave
Heater-cathode type power rectifier in the miniature construction. Its low voltage drop and small size adapt it to use with vibrator-type inverters in automobile receivers.
T-6E5-TUBULAR Vacuum Tube - 6E5, Indicator, Tubular Glass
High-vacuum, heater-cathode type of tube designed to indicate visually the effect of change in the controlling voltage. Essentially a voltage indicator and as such is particularly useful to facilitate exact tuning of a radio receiver.
T-12SL7GT Vacuum Tube - 12SL7GT, Triode, Dual, HI-MU
High-mu twin triode designed for use in resistance-coupled circuits as a voltage amplifier or phase inverter. Except for heater characteristics and ratings, the 12SL7GT is identical to the 6SL7GT.

T-1U5 Vacuum Tube - 1U5, Diode, Sharp Cut-Off Pentode
Miniature diode sharp-cutoff pentode designed for use as a combined detector, audio-frequency amplifier, and automatic-volume-control tube in compact, battery-operated receivers.
T-5AR4-GEN Vacuum Tube - 5AR4 / GZ34 / U77, Genalex Gold Lion
Genalex Gold Lion U77 / GZ34 full-wave rectifier tube. Made in Russia.
T-6146B_8298A 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.
T-6550-EH 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
T-6SC7 Vacuum Tube - 6SC7, Triode, Dual, HI-MU
High-mu twin triode designed primarily for use as an AF voltage amplifier. Featuring a special shielding arrangement to reduce hum, the tube is well suited for low-level audio amplifier service.
T-12DQ6B_12GW6 Vacuum Tube - 12DQ6B / 12GW6, Beam Power Amplifier
Beam power pentode primarily designed for use as the horizontal-deflection amplifier in television receivers.
