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.
New Old Stock (NOS)
Our new-old-stock tubes were made in the U.S. by the major manufacturers, with several types made in Western Europe or Japan. All NOS tubes are tested and guaranteed.
Combined high-mu triode and double diode using the 8 pin lock-in construction. It is designed for use as a diode detector, AVC rectifier, and an impedance or resistance coupled amplifier.
$6.40
The T-12SK7 is the same as the 6SK7 except for heater ratings.
$6.90
Filament type double grid power amplifier tube. It is especially designed for class B operation to give a large amount of undistorted power output.
$34.75
Triode-heptode for use in F.M., AM/FM, A.M, and television receivers.
$8.90
Consists of two diodes and a pentode utilizing a common cathode. It is designed for service as a combined detector, AVC rectifier, and pentode amplifier.
$7.90
Twin output pentode for use as an audio-frequency output tube in stereophonic radio receivers and recorders, push-pull output tube and as line frequency oscillator and reactance tube in television receivers.
$69.95
The 6K6G is an indirectly heated cathode type power amplifier pentode designed for service in the output stages of AC, AC/DC and storage battery operated receivers.
$13.95

$14.95
Out of Stock
Pentagrid converter designed for service as a combined oscillator and mixer in AC, storage battery, and AC-DC operated receivers
$49.90
High-vacuum, heater-cathode type of tube designed to indicate visually the effect of change in the controlling voltage. Essentially a voltage indicator and as such is particularly useful to facilitate exact tuning of a radio receiver.
$39.90
Compactron beam-power pentode designed for use as the horizontal deflection amplifier in television receivers.
$19.90
Power pentode for output stages of high fidelity audio-amplifiers and radio receivers
