# 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 - 12DW7 / ECC832, JJ Electronics, Dual Triode
In the 12DW7/ECC832, Section 1 of the tube (pins 6, 7, and 8) is the high gain 12AX7/ECC83 spec (gain factor 100) and Section 2 (pins 1, 2, and 3) is the low gain 12AU7/ECC82 spec (gain factor 17).
Starting at $12.95 Vacuum Tube - 6BE6 / EK90, Heptode Miniature heptode primarily designed to perform the combined functions of the mixer and oscillator in superheterodyne circuits in both the standard broadcast and FM bands.$6.90
Vacuum Tube - 12BE6 / HK90, Heptode
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 Vacuum Tube - 6C4 / EC90, Triode, Medium-MU Miniature, medium-mu triode suitable for use in a wide variety of general purpose applications. It is especially useful as a local oscillator in high-frequency and very-high-frequency receiver circuits.$6.90
Vacuum Tube - 50L6GT, Beam Power Amplifier
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 Vacuum Tube - 6AN8A, Triode, Pentode Medium mu triode and a sharp cutoff pentode. The pentode section may be used as an IF amplifier or a reactance tube; the triode section is well suited for use in low-frequency-oscillator, sync clipper, sync separator, and phase splitter circuits.$15.90
Vacuum Tube - 12AV6, Diode, Dual Triode
Combines a high mu triode and two independent diode units in the 7-pin miniature construction. It permits a single tube to function as detector, AVC rectifier, and audio amplifier.
$5.90 Vacuum Tube - 35L6GT, Beam Power Amplifier 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.$8.90
Vacuum Tube - 50C5, Beam Power Amplifier
Miniature beam pentode primarily designed for use in the audio-frequency power-output stage of radio receivers. The tube features high power sensitivity and high efficiency at relatively low plate and screen voltages
