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.
Miniature remote-cutoff pentode designed for use as a radio-frequency or intermediate frequency amplifier in compact, battery-operated equipment.
$4.90
Miniature diode sharp-cutoff pentode designed for use as a combined detector, audio-frequency amplifier, and automatic-volume-control tube in compact, battery-operated receivers.
$6.90
Miniature, duplex-diode, high-mu triode designed for use as a combined detector, amplifier, and automatic-volume-control tube

Tung Sol 7591A beam-power tube. Made in Russia.
Starting at $31.95
The 0B2 is a two-electrode, inert-gas-filled cold cathode miniature tube intended for use as a voltage regulator.
$5.90
Metal pentagrid converter. It is intended to perform the combined functions of the mixer and oscillator in superheterodyne receivers, especially those of the all-wave type. The 6SA7 is constructed to provide excellent frequency stability.
$3.90
Super Premium power beam tetrode & exact copy of the original clear glass KT66, used in the early Marshall amps which created Eric Clapton’s "Bluesbreaker" Tone.” Full sound with improved bass response and shimmering top-end.
- Originally a British equivalent to 6L6 and a mainstay of the British hi-fi industry
- Used in 50s - 60s hi-fi favorites such as the Heath W-5M and many Leak amplifiers
Starting at $40.95
Miniature, filamentary, sharp-cutoff pentode intended for radio frequency or intermediate frequency amplifier use in battery-operated receivers.
$6.90
Superior high-power Octal Beam Tetrode, suitable for any amp using 6550 or KT88. Designed to hold up in even the most punishing environment of high powered bass amps, such as Ampeg SVT. With 42 watts of plate dissipation in tetrode operation and 44 watts in triode, power is improved even over desirable vintage types.
Starting at $38.95
Twin-diode with individual cathodes brought out to separate base pins. The 6H6 is designed for service as a diode detector, automatic volume control rectifier, or as a low current power rectifier
$4.90
Electro-Harmonix 7868 power pentode tube with “novar” base. Made in Russia.
Starting at $29.95
Tung Sol 5751 dual triode preamp tube. Made in Russia. NOS specs call the 5751 a “special 12AX7” having a high-mu amplification factor of 70.
$24.95
Also known by US military identifier VT-197A. The 5Y3GT is a filamentary twin-diode designed for full-wave rectifier operation in power supplies that have d-c output current requirements up to approximately 125 milliamperes. RCA brand.

Starting at $24.85
Pentode amplifier designed for application in power output stages of receivers
$12.95
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
Medium mu triode and sharp cutoff pentode in the 9 pin miniature construction. It is intended for use as a combined VHF oscillator and mixer in television receivers.
$9.90
Mullard 12AT7 / ECC81 dual triode preamp tube. Made in Russia.
$22.50
Triode-heptode for use in F.M., AM/FM, A.M, and television receivers.
$8.90
Sharp cut-off general purpose amplifier. With the exception of heater and capacitance ratings, the electrical characteristics are similar to those of the 6C6.
