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.
Vacuum Tube - 6136 / 6AU6WA, Pentode, Sharp Cut-Off
Miniature sharp-cutoff pentode designed primarily for use as a high gain radio-frequency or intermediate-frequency amplifier. Low grid-plate capacitance and high transconductance make it especially suited for high-frequency wide-band applications.
Vacuum Tube - KT88, Genalex Gold Lion
KT88 power tube reissue of Genalex Gold Lion. Made in Russia.
In 1957 Marconi-Osram Valve Co. (Genalex) introduced the "King of Power Tubes", the legendary Gold Lion KT88. This tube became the heart and soul of such classics as the Dynaco Mark III, McIntosh MC275, and Marshall Major. Unfortunately, Genalex ceased tube production in the early 1980s and the Genalex Gold Lion KT88 has become very expensive and hard to find.
After extensive research and engineering, New Sensor Corp. has reissued the famed Genalex Gold Lion KT88.
Starting at $58.50
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.
Vacuum Tube - 6L6, Electro-Harmonix
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.
Starting at $21.75
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
Vacuum Tube - 12AT7 / B739, Genalex Gold Lion, Gold Pin
Genalex Gold Lion ECC81/B739 (12AT7) dual triode preamp tube with gold pins. Made in Russia. Original Genalex Gold Lion ECC81/B739 tubes are considered the best 12AT7 types ever made. They are also among the rarest types available. They exhibit a large detailed soundstage that is characterized by an expressive midrange, deep tight bass, and a smooth extended high end. The reissue Genalex Gold Lion ECC81/B739 recreates the sound signature of the original. This tube features balanced sections and gold plated pins.

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.
Vacuum Tube - 5726 / 6AL5W, Dual Diode
Twin diode miniature type intended for applications where dependable performance under shock and vibration is paramount. The 5726 is a "premium" version of the 6AL5W

Vacuum Tube - 5842 / 417A, Triode
9-pin miniature triode with an indirectly heated cathode. It is intended primarily for grounded grid operation in the input stage of broad band amplifiers.
Vacuum Tube - 12BH7A, Triode, Dual, Medium MU
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.
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 - 6V6GT, Mullard Reissue
Mullard 6V6GT tube. Made in Russia. This valve is built to stand the high voltages encountered in the Fender Deluxe Reverb and other guitar amplifiers that ran the valves above the published specification. The smooth and balanced frequency response also makes it suitable for hi-fi use.
Starting at $28.50
Vacuum Tube - 12BV7 / 12BY7A, Pentode
Miniature power pentode designed primarily for use as the video output amplifier in television receivers. Like the 12BY7, it features high transconductance, high power sensitivity, and low interelectrode capacitances.
Vacuum Tube - 6C8G, Dual Triode
General purpose twin triode having two independent units, with all electrodes brought out to separate terminals.
Vacuum Tube - 12BZ7, Triode, Dual, Hi-mu
Heather-cathode type high-mu twin triode of miniature construction designed for use as a resistance-coupled voltage amplifier or phase inverter and blocking oscillator.
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.
Vacuum Tube - 6386-LGP, JJ Electronics, Gold Pin
The impossible search for tubes to use in your high end studio equipment is over. JJ Electronic has spared no effort in creating a tube that meets the quality demands of working studios with the JJ 6386-LGP. This solidly constructed tube features gold pins.
Vacuum Tube - 6AW8A, Triode, Pentode
Miniature tube containing a high-mu triode and a sharp-cutoff pentode. The triode section is intended for service as a sync separator and the pentode section as a video amplifier.
Vacuum Tube - 12SA7, Heptode
Pentagrid converter designed to minimize frequency drift. They are intended for service as combined oscillators and mixers in AC, storage battery, and AC/DC operated superheterodynes.
Vacuum Tube - 12SK7, Pentode, Remote Cut-Off
The T-12SK7 is the same as the 6SK7 except for heater ratings.
Vacuum Tube - 5AR4 / GZ34 / U77, Genalex Gold Lion
Genalex Gold Lion U77 / GZ34 full-wave rectifier tube. Made in Russia.
Vacuum Tube - 6CA7, Electro-Harmonix
Electro-Harmonix 6CA7 Vacuum Tube Big bottle beam-tetrode version of EL34. Perfect EL34 replacement for Musicman amplifiers.
