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.
Filamentary twin diode designed for use as a full-wave rectifier in the power supply of television receivers or other equipment which has high direct-current requirements. The 5U4GB may be used a replacement for either the 5U4G or the 5U4GA.
$44.90
Cold cathode, gas-filled diode of miniature construction designed for reliable service as a voltage regulator. It has an operating current range of 5 to 30 milliamperes over which it maintains a substantially constant operating voltage of 150 volts.
$5.25
Twin triode designed for service as a class B power amplifier and as a class A driver
$6.90
Heater-cathode type of tube intended for use in compact, light-weight equipment. Because of its small size, the 6AK6 can be used singly or in push-pull to effect a more compact design of power-line receivers.
$4.90
Pentode power amplifier using the miniature construction. It is intended for service in AC and storage battery operated receivers where moderate power sensitivity and power output is desired.
$9.90
Pentode amplifier designed for application in power output stages of receivers
$59.90
Miniature, high-mu, twin triode primarily designed for use in low-level stages of high-gain audio-frequency amplifiers. Use of the 7025 in this application is advantageous because of its low hum output.
$59.95

Triode-pentode designed primarily for high fidelity audio applications. The pentode section is particularly suited to preamplifier service while the triode section is intended for use as a phase inverter.
$69.90
Full-wave rectifier designed for use in three-way portable receivers. Except for a common heater, the rectifier sections are separate, permitting the tube to be used as a full-wave or a half-wave rectifier, or as a voltage doubler.
$7.90
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
Electro-Harmonix 12DW7 dual triode preamp tube. Made in Russia.
12DW7 combines one triode of 12AX7 and one triode of 12AU7 in a dual triode package. System 1 (pins 6, 7, 8) is the high-mu 12AX7 triode and system 2 (pins 1, 2, 3) is the medium-mu 12AU7 triode.

$41.70
Filament type triode power amplifier designed for service in the output stage of audio amplifiers where high output and low harmonic distortion are desired.
$139.90
Miniature type triode-pentode designed for use as an AF amplifier by triode section and AF power amplifier by pentode section in radio receivers.
$5.90
Cathode type high vacuum rectifier designed for full-wave applications. The cathode is connected internally to the heater.
$29.90
Contains three high-mu triodes with separate pin connections for all three cathodes, grids, and plates in a compact T-9 glass envelope with the novel 12 pin base.
$99.90
Dissimilar double triode utilizing the 9T9 bulb and pin configuration. The tube is designed to serve as a combined vertical deflection oscillator and amplifier.
$7.90
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
High-mu twin triode designed for use in resistance-coupled circuits as a voltage amplifier or phase inverter.
$34.90
Pentode voltage amplifier using the lock-in construction. It is designed for RF or IF service in AC/DC receivers.
$5.90
Combined high-mu triode and double diode using the 8 pin lock-in construction. It is designed for use as a diode detector, AVC rectifier, and an impedance or resistance coupled amplifier.
