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 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.
$16.90
The 5Z3 is designed for service as a power rectifier in AC operated receivers which require high currents
$24.90
The 5Z4 is designed for service as a power rectifier in AC operated receivers.
$8.90
Full-wave high-vacuum rectifier for use in power supplies of moderate current requirements. The tube incorporates a unipotential cathode which is internally connected to the filament.
$49.90
Miniature full-wave high-vacuum rectifier intended for use in power supplies which have low d-c output-current requirements.
$11.90
Full-wave rectifier of the heater-cathode type intended for use in AC operated and automobile receivers. Because of its heater-cathode construction it has the same heating time as that of other heater-cathode types in the receiver.
$5.90
Isa full-wave high-vacuum rectifier designed for damper service in television deflection circuits. It can also be used in conventional rectifier applications.
$11.90
Miniature, heater-cathode, twin diode for full-wave rectifier operation. High output current and small size make it especially suitable for compact amplifier designs.
$24.90
New Old Stock 6W5-G. Full-wave high-vacuum rectifier.
$19.95
Miniature heater-cathode type twin diode designed for full-wave rectifier operation in compact power supplies. The tube is intended for service in automobile and a-c radio receivers.
$12.95
The 6X5G is an indirectly heated full-wave rectifiers for use in equipment where the current drain does not exceed 70 mA.
$14.80
Out of Stock
Cathode type rectifier designed particularly for use in automobile receivers.
