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).

$23.90
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.
$23.95
The 12AT7 is a miniature, high-mu, twin triode designed for use as a grounded-grid radio-frequency amplifier or as a combined oscillator and mixer at frequencies below approximately 300 megacycles.

$24.90
Frame-grid twin triode designed for low supply voltage applications. It is especially suitable for instrumentation/industrial use as a direct-coupled wide band amplifier and for automobile radio as an RF amplifier and self-oscillating mixer.
$24.90
Miniature medium-mu twin triode suitable for use in a wide variety of general-purpose applications. It is particularly useful as a vertical-deflection oscillator and horizontal-deflection oscillator in television receivers.
$24.90
The new Tube Amp Doctor premium selected 12AX7 /ECC83-WA is a low-noise and low microphonic version of the 12AX7. The ECC83-WA Premium Selected has a balanced tone with a notable emphasis of the mids. The overall linear sound offers great string attack and chord separation. The low end is well defined. The result is a tone that works well in both modern amps but also vintage guitar amplifiers. If the ECC83-WA is used in hi-fi audio amplifiers, the tube adds a musical clarity and presence to the signal. The new TAD™ ECC83-WA is a miniature, high-mu twin triode, selected and recommended for guitar amps to improve overall responsiveness and dynamics. Great for guitar clean tones with a distinct pick attack and pronounced upper mids to cut through every mix. Crunchy tones still feature a very good string separation which is also ideal for fully saturated sounds and modern amplifiers with a tight bass response.
$24.95
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
Heater-cathode type duplex-diode high-mu triode designed for use as a combined detector, audio-frequency amplifier and automatic-volume-control tube
$27.45
High-mu power output triode designed for service in dynamic coupled circuits using a type 76, 6P5GT/G or 6J5GT/G as a driver. Two 6AC5Gs may be used as a zero bias class B amplifier.
$27.55
High current, twin power triode widely used in electronically regulated power supplies. The high perveance of this tube permits it to pass large currents at low plate voltages, thus providing for efficient series regulation. Shouldered glass (ST-16) envelope.
$27.90
General purpose triode designed for service as an oscillator, detector, or amplifier
$28.50
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.
