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 - 1620, Pentode
Metal, sharp-cutoff pentode for use as a high-gain, audio-frequency amplifier or as a biased detector. The tube is a low-microphonic version of the 6J7 to which it is otherwise identical.

Vacuum Tube - 5654 / 6AK5W, Pentode, Sharp Cut-Off, RF
Miniature sharp-cutoff pentode for use as a wide-band, high-frequency amplifier. It is also useful in video and audio amplifiers, oscillators, mixers, frequency multipliers, and cathode followers.
$4.90
Vacuum Tube - 5672 / DL69, Pentode
Subminiature pentode for use as an A.F. power amplifier in portable equipment.
$6.90
Vacuum Tube - 5693, Pentode, Sharp Cut-Off
Sharp cutoff pentode intended for critical industrial applications where 10,000 hour life, extreme uniformity, rigid construction, and exceptional stability are paramount.

Vacuum Tube - 5749 / 6BA6W, Pentode, Remote Cut-Off
Miniature remote-cutoff pentode intended for use as a high-gain radio frequency or intermediate-frequency amplifier. Its remote-cutoff characteristic makes it suitable for use in circuits to which it is desired to apply automatic-gain-control.
$4.90
Vacuum Tube - 5879, Pentode, Sharp Cut-Off
Sharp-cutoff pentode of the 9-pin miniature type intended for use as an audio amplifier in applications requiring reduced microphonics, leakage noise, and hum.
$12.90
Vacuum Tube - 6084 / E80F, Pentode
Special quality pentode designed for use as an amplifier
$49.90
Vacuum Tube - 6136 / 6AU6WA, Pentode, Sharp Cut-Off
Miniature sharp-cutoff pentode designed primarily for use as a high gain radio-frequency or intermediate-frequency amplifier. Low grid-plate capacitance and high transconductance make it especially suited for high-frequency wide-band applications.
$9.90
Vacuum Tube - 6267 / EF86, Pentode, Sharp Cut-Off
Pentode intended for use as A.F. amplifier.
$49.95
Vacuum Tube - 6678 / 6U8A, Triode, Pentode
Miniature tube containing a medium-mu triode and a sharp-cutoff pentode. It is especially suited for use as a combined oscillator and mixer at very high frequencies.
$9.90
Vacuum Tube - 7189, Pentode, Beam
New-Old-Stock (NOS) tube. The 7189 is a power-amplifier pentode designed for use in the audio-frequency power output stage of television and radio receivers and high-fidelity amplifiers. It differs from the 7189A in having a lower screen-voltage rating and no internal connections to pins 1 and 6. It cannot be used as a replacement for a 7591A in most situations.
$60.90
Vacuum Tube - 7189A, Pentode, Beam
New-Old-Stock (NOS) tube. The 7189A is a power-amplifier pentode designed for use in the audio-frequency power output stage of television and radio receivers and high-fidelity amplifiers. It differs from the 7189 in having a higher screen-voltage rating and in specifying the internal connections to pins 1 and 6. See T-7189
$60.90
Vacuum Tube - 7199, Triode, Pentode
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.

Vacuum Tube - 7534 / E130L, Pentode
Special quality tube designed for use as a wide band amplifier, cathode follower, series regulator tube for stabilized DC supply and output tube.
$49.90
Vacuum Tube - 7868, Pentode, Power Amplifier
Power pentode for output stages of high fidelity audio-amplifiers and radio receivers
$77.90
Vacuum Tube - 8233 / E55L, Pentode, Power Amplifier
Special quality pentode designed for use as a wide band output tube.

Vacuum Tube - EL34 II, JJ Electronics, Pentode
A different construction of the classic EL34 tube that offers a different tonal palette than the original. This tube has a more compact plate structure than standard EL34’s. The JJ EL34 II has an increased low to low-mid end with plenty of headroom to spare. The JJ EL34 II is stronger than the original but not harsh sounding in any way.
Starting at $25.50
Vacuum Tube - 6BQ5 / EL84, Pentode, Power
Power amplifier pentode designed for use in the audio-frequency power output stage of television and radio receivers and in high fidelity amplifiers.
