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 - 1H5GT-G, Diode, Triode, High MU
Tube containing a single diode and a high-mu triode in one bulb. It is designed for service as a diode detector, AVC rectifier, and as a resistance-coupled amplifier.
$3.90 Vacuum Tube - 25Z6GT, Dual Rectifier Heater-cathode type full-wave high-vacuum rectifier doubler tube designed for use in the power supply of a-c or a-c/d-c receivers. Eletrically the 25Z5, 25Z6, and 25Z6GT are identical.$5.90
Vacuum Tube - 35Z3, Rectifier, Half Wave
New-Old-Stock (NOS) tube. The 35Z3 is a half-wave high-vacuum rectifier designed for use in a-c/d-c receivers. Electrically the 35Z3 is equivalent to the 35Z5GT except that the heater of the 35Z3 is not tapped for operation of a panel lamp. The 35Z3 is a loctal-based tube (compared to the octal base of the 35Z5GT.)
$5.90 Vacuum Tube - 6AH6, Pentode, Sharp Cut-Off Miniature sharp-cutoff pentode. Its high transconductance and low input and output capacitance adapt it to use as a wide-band amplifier or as a reactance tube.$3.55
Vacuum Tube - 78, Pentode, Remote Cut-Off
Heater-cathode type pentode amplifier tube with remote cut-off characteristics and is designed for use as a radio frequency or intermediate frequency amplifier in a-c or battery operated equipment
$7.90 Vacuum Tube - 6SL7, Tung-Sol Reissue Tung Sol 6SL7 dual triode preamp tube. Made in Russia. The best current production 6SL7 available. NOS performance and sound at a fraction of the price. Sweeten up the preamp section of that Vintage Ampeg B-15.$39.50
Vacuum Tube - 12SG7, Pentode, Semi-Remote Cut-Off
Semi-remote cut off pentode voltage amplifier in the octal metal construction. It features high transconductance with low grid-plate capacitance and a dual cathode connection to minimize effects of common cathode circuit coupling.
$5.35 Vacuum Tube - 5751, Sovtek Sovtek 5751 dual triode.$19.50
Vacuum Tube - 5963 / 12AU7A, Dual Triode
Miniature, medium-mu twin triode for use as a frequency divider in computer applications.
$9.90 Vacuum Tube - 5V4GA, Rectifier, Full Wave High vacuum rectifier intended for use in full-wave applications. The tube incorporates an indirectly heated cathode which is internally connected to the heater$29.90
Vacuum Tube - 6BH6 / E90F, Pentode, Sharp Cut-Off
Miniature sharp-cutoff pentode primarily designed for use as a high-gain radio-frequency or intermediate-frequency amplifier. Features include low grid-plate capacitance, relatively high transconductance, and low heater current.
$5.90 Vacuum Tube - 6BQ7A / 6BZ7, Dual Triode Miniature, medium-mu twin triode primarily designed for use as a cascode, radio-frequency amplifier in very high frequency television tuners. In this application, its performance is characterized by high gain and low noise figure.$3.55
Vacuum Tube - 6N7, Triode, Dual, Power Amplifier
Heater-cathode type twin triode designed for use as a class B power amplifier in the output stage of a-c or battery operated equipment. It may also be used in a biased detector, oscillator phase inverter or class A amplifier
$7.90 Vacuum Tube - 5R4WGA-B-Y, Rectifier, Full Wave Long life, ruggedized, reliable full wave rectifier tube.$11.95
Vacuum Tube - 6F5GT, Triode, HI MU
General purpose high-mu triode. It is designed for service as a high gain resistance coupled amplifier in AC and AC - DC operated receivers.
$8.55 Vacuum Tube - 6GK6, Beam Power Amplifier General-purpose power pentode that may be used either in audio output amplifier or video power output amplifier stages of television receivers.$10.90
Vacuum Tube - 7A7, Pentode, Remote Cut-Off
Pentode voltage amplifier using the lock-in construction. It is designed for RF or IF service in AC/DC receivers.
$5.90 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.$43.95
Vacuum Tube - KT77, Genalex Gold Lion
Genalex Gold Lion KT77 beam-power tetrode tube. Made in Russia.
A beam tetrode with an absolute maximum anode dissipation rating of 32 watts. The KT77 is designed for use in the output stage of an af amplifier. Two valves in Class AB1 give a continuous output of over 70 W.
Starting at $50.95 Vacuum Tube - 12DT8, Triode, Dual General-purpose high-mu twin triode of the 9-pin miniature type intended for use as an rf amplifier and as a combined oscillator-mixer in fm tuners. This tube is also useful in a wide variety of applications in radio and television receivers.$9.90
Vacuum Tube - 25Z5, Rectifier, Dual, ST Glass
Heater-cathode type full-wave high-vacuum rectifier doubler tube designed for use in the power supply of a-c or a-c/d-c receivers. Eletrically the 25Z5, 25Z6, and 25Z6GT are identical.
