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.
Pentode amplifier having a remote control grid characteristic and utilizing the miniature construction. As a RF amplifier, it is characterized by high transconductance and low grid-plate capacitance.

Tung Sol 12AU7W / 6189 dual triode preamp tube. Made in Russia.
$21.95
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
Miniature remote-cutoff pentode intended for use as a high-gain radio frequency or intermediate-frequency amplifier. Its remote-cutoff characteristic makes it suitable for use in circuits to which it is desired to apply automatic-gain-control.
$4.90
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.

The Sovtek 6550WE was designed to be the finest 6550 ever produced. Thicker plates, improved heat dissipation, higher transconductance, and increased linearity are just some of the inherent aspects of the new Sovtek super 6550s. The resulting performance advantages include 5% higher output power, increased reliability, greater headroom, and superior tone. The 6550WE features a metal-ringed base for increased power-handling capabilities.

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.
$145.95
Dissimilar double triode in the 9-pin miniature construction. It is especially suitable for applications requiring a high gain voltage amplifier and a cathodyne type phase-inverter.
$24.95
Mullard 12AU7 / ECC82 dual triode preamp tube. Made in Russia.
$22.95
The TAD 6L6GCM-STR REDBASE is Tube Amp Doctor's latest 6L6GC; designed and built to be the best 6L6 type tube ever manufactured. A high claim, but Tube Amp Doctor is sure that they have achieved exactly that. In terms of sound, the TAD 6L6GCM-STR REDBASE produces the powerful but always defined bass response known from the legendary american built NOS RCA 6L6GC, with clear, unobtrusive and yet transparent highs.
Starting at $37.95
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
$6.90
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
Miniature half-wave rectifier for use in line-operated equipment having series-connected heaters. The heater is tapped to permit operation of a panel lamp.
$7.90
Miniature pentagrid converter designed to perform simultaneously the combined functions of the mixer and oscillator in superheterodyne receivers. The tube is suitable for use in the standard broadcast and FM bands.
$7.90
Metal duplex-diode high-mu triode. It is intended primarily for use as a combined detector, amplifier, and automatic-volume-control tube in radio receivers.
$6.90
The JJ Electronic 7027A offers the same reliability and tone as the JJ 6L6GC but with the correct pinout for vintage amplifiers that use 7027 tubes like older Ampegs. At 30W, this tube delivers plenty of headroom. The highs are clear and responsive with warm mids and tight solid lows. Known for their reliability and articulation, the JJ 7027A is a great option guitar amplifiers and Hi-Fi stereo equipment.
Starting at $23.95
Tweed Up Your Amp! Vintage tone for original vintage Fender tweed amps. The original tube for all those Fender® tweed amps from the 50s. Brings back the original sound to your tweed amp.
$25.50
Tung Sol 5751 dual triode preamp tube. Made in Russia. NOS specs call the 5751 a “special 12AX7” having a high-mu amplification factor of 70.
$26.75
General-purpose triode designed for use as a detector, amplifier, or oscillator. Features include a relatively high transconductance and a medium amplification factor.
$8.90
Miniature high-mu twin triode each section of which has an individual cathode connection. The tube is especially suited for use as a grounded-grid amplifier or as a frequency converter at frequencies below approximately 300 megacycles.
$10.95
Miniature remote-cutoff pentode designed for use as a radio-frequency or intermediate frequency amplifier in compact, battery-operated equipment.
