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.
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

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
The 5U4G is designed for service as a power rectifier in AC operated receivers which require high currents
$49.90
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
Rugged full-wave filamentary type rectifier designed for use in applications requiring resistance to shock or vibration.
$34.90
Ruggedized heater-cathode type double diode using the 9 pin miniature construction. It is suitable for use in half or full wave rectifier applications or as a voltage doubler.
$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
Filamentary full-wave high-vacuum rectifier designed for use in the power supply of a-c operated equipment
$29.90
Cathode type high vacuum rectifier designed for full-wave applications. The cathode is connected internally to the heater.
$29.90
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
Half-wave high-vacuum rectifier which may be used with either choke or condenser input to the filter.
$27.35
Power rectifier with low internal voltage drops. It is designed for service in AC operated receivers that require high currents
$25.60
The 5R4GY is designed for rectifier use in equipment requiring a high peak inverse voltage rating. Satisfactory operation of this tube type under conditions falling within area 1 on curve no 1 may be obtained without filament preheating.
$24.90
Miniature, heater-cathode, twin diode for full-wave rectifier operation. High output current and small size make it especially suitable for compact amplifier designs.
