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 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
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
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
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
Beam power amplifier designed for service in the output stage of 600mA series heater operated TV receivers. It has high power sensitivity and high power output with comparatively low supply voltage.
$9.90
The 5X4 is designed for service as a power rectifier in AC operated receivers which require high currents
$12.90
