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.

$19.90
Triple grid general purpose detector amplifier. With the exception of capacitance, its electrical characteristics are identical with those of the 6J7G and 6J7GT.
$8.90
Triode intende for use as a grounded grid UHF amplifier for bands IV and V.
$7.90
High-perveance beam power pentode designed for use as a horizontal deflection amplifier tube in high efficiency deflection circuits of television receivers.
$9.90
Sharp cut-off general purpose amplifier. With the exception of heater and capacitance ratings, the electrical characteristics are similar to those of the 6C6.
$11.90
Beam power tube with separate grid-no.3 base-pin terminal for "snivets" control. It is designed for horizontal-deflection-amplifier service in Low-B+ black-and-white TV receivers.
$49.90
Consists of a triode oscillator and a hexode mixer in a common envelope. Reduces interaction between the oscillator and mixer sections and makes for stable operation in superheterodyne receivers on the high frequencies as well as the broadcast band.
$6.90
The 6L6 is designed with high power sensitivity and high efficiency for service in the output stages of AC receivers. They are capable of delivering an output at all power levels with a very low percentage of harmonic distortion.
$29.90
Mixer tube designed for service with a separate oscillator as the first detector in superheterodyne receivers. The control grid is of the remote cut-off type which allows the use of AVC and minimizes cross-modulation.
$5.90
Heater-cathode type twin triode designed for use as a class B power amplifier in the output stage of a-c or battery operated equipment. It may be used in other applications such as a biased detector, oscillator phase inverter or class A amplifier
$10.90
Pentagrid metal tube designed for use as a combined mixer and oscillator in superheterodyne circuits. Especially useful in FM receiver service below 120 megacycles.
$6.65
Compactron containing two medium-mu triodes and one high-mu triode.
$10.95
Sharp cut-off pentode voltage amplifier designed for use in television or other high-frequency amplifiers where the low impedance circuits required result in low gain which may be partially compensated for by use of a high transconductance tube.
$13.90
Heater type vacuum twin diode using the lock-in construction. It is intended for use as a full-wave rectifier in either AC or storage operated equipment where economy of heater power is desired.
$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 $67.35
The 10BQ5 is an output pentode designed for application in medium power hi-fi amplifiers. A pair of tubes in class AB, push-pull conventional operation yields an output of up to 17 watts at 4% distortion (without feedback).
$6.90
The type 12SC7 is a twin-triode amplifier designed for use as an audio amplifier or phase inverter. Special shielding arrangement in the base permits operation at a low hum level.
$5.90
Semi-remote cut off pentode voltage amplifier in the octal metal construction. It features high transconductance with low grid-plate capacitance and a dual cathode connection to minimize effects of common cathode circuit coupling.
$5.35
Pentagrid converter designed for use as a combined oscillator and mixer in superheterodyne receiver. The electrical characteristics of the 14Q7 are similar to those of the 12SA7
$5.90
Transmitting triode for oscillator applications requiring unusually stable characteristics.
$14.90
Beam power amplifier designed primarily for use in the output stage of a-c/d-c receivers. It has high power sensitivity and high efficiency at relatively low plate and screen voltages.
$6.90
New-Old-Stock (NOS) tube. The 35Z3 is a half-wave high-vacuum rectifier designed for use in a-c/d-c receivers. Electrically the 35Z3 is equivalent to the 35Z5GT except that the heater of the 35Z3 is not tapped for operation of a panel lamp. The 35Z3 is a loctal-based tube (compared to the octal base of the 35Z5GT.)
$5.90
Miniature high-mu twin triode each section of which as an individual cathode connection suited for use in resistance-coupled voltage amplifiers, phase inverters, multivibrators, andindustrial-control circuits where high voltage gain is desired.
