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.
In the ECC823, Section 1 of the tube (pins 6, 7, and 8) is the low gain 12AU7/ECC82 spec (gain factor 17) and Section 2 (pins 1, 2, and 3) is the high gain 12AX7/ECC83 spec (gain factor 100).

$6.90
Miniature power pentode designed primarily for use as the video output amplifier in television receivers. The tube exhibits high transconductance, high power sensitivity, and low interelectrode capacitances.
$7.90
Medium-mu triode using the lock-in construction. It is designed for use as an oscillator, detector, or amplifier. It is characterized by moderately high transconductance. It is particularly applicable for service in the higher frequencies.
$9.90
Miniature pentagrid-converter designed for use as a combined mixer and oscillator in superheterodyne circuits. Because of its small size and high operating efficiency, the 1R5 is especially adapted for compact, battery-operated equipment.
$5.90
Miniature 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.
$15.90
General purpose medium-mu double triode using the 9-pin button all-glass construction. The tube is characterized by high perveance and high emission capabilities.
$19.90
Electro-Harmonix 7868 power pentode tube with a magnoval style base. Made in Russia.
Starting at $53.55
Filamentary type sharp cut-off pentode voltage amplifier. It is designed for service in low-drain battery-operated receivers as an RF, IF, or AF amplifier.
$5.90
The 3A5 is intended for use in high frequency applications. The relatively large filament employed in the 3A5 enables it to supply the high peak currents required in RF power applications.
$5.90
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.
$50.10
Medium-mu twin triode suitable for use in a wide variety of general-purpose amplifier and phase-inverter applications. It is also especially useful as a blocking oscillator, multivibrator, or vertical deflection amplifier in television receivers.
$22.95
Tung-Sol has reissued the rare 7189, a high fidelity audio specific variation on the EL84 tube. In addition to the increased fidelity, the 7189 features a higher maximum plate voltage rating of 400V. These tubes are great for both guitar and HiFi amplifiers and can be used in any EL84 or 6BQ5 position.
Starting at $46.60
Heater-cathode type beam-power amplifier tube designed for use in the audio-output stage of ac or ac/dc receivers.
$4.90
