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.
The 0Z4A is a gas-filled, double diode employing an ionic-heated cathode. Its principal application is as a full-wave power rectifier in equipment with vibrator type power supplies.
$3.90
Glass-type half-wave high-vacuum rectifier with an indirectly heated cathode. It is especially designed for use in a-c/d-c and automobile receivers.
$7.90
Heater-cathode twin diode designed for full-wave rectifier operation. High output current and small size make this tube especially suitable for compact amplifier designs.
Starting at $52.90

Long life, ruggedized, reliable full wave rectifier tube.
$11.95
The 5T4 is designed for service as a power rectifier in AC operated receivers.
$19.95
Filamentary twin diode designed for use as a full-wave rectifier in the power supply of television receivers or other equipment which has high direct-current requirements. The 5U4GB may be used a replacement for either the 5U4G or the 5U4GA.
$44.90
The 5U4G is designed for service as a power rectifier in AC operated receivers which require high currents
$49.90
Cathode type high vacuum rectifier designed for full-wave applications. The cathode is connected internally to the heater.
$29.90
High vacuum rectifier intended for use in full-wave applications. The tube incorporates an indirectly heated cathode which is internally connected to the heater
$29.90
The 5X4 is designed for service as a power rectifier in AC operated receivers which require high currents
$12.90
Filamentary twin-diode designed for full-wave rectifier operation in power supplies that have D-C output current requirements up to approximately 125 milliamperes.
$29.45
The 5Y4G is designed for use as a power rectifier in AC operated receivers.
$24.90
Full-wave vacuum rectifier. The 5Y4GT is the same as the 5Y4GA except for mechanical design.
