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, for unipotential cathode. 117 volts AC-DC.
$4.90
Vacuum Tube - 5Y3GT, Rectifier, Full Wave
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
Vacuum Tube - 5V4G, Rectifier, Full Wave, ST Glass
Cathode type high vacuum rectifier designed for full-wave applications. The cathode is connected internally to the heater.
$29.90
Vacuum Tube - 1V / 6Z3, Rectifier
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
Vacuum Tube - 35Y4, Rectifier, Half Wave

Vacuum Tube - 25Z5, Rectifier, Dual, ST Glass
Heater-cathode type full-wave high-vacuum rectifier doubler tube designed for use in the power supply of a-c or a-c/d-c receivers. Eletrically the 25Z5, 25Z6, and 25Z6GT are identical.
$5.90
Vacuum Tube - 5AU4 / 5V3A, Rectifier, Full Wave
Filamentary full-wave high-vacuum rectifier designed for use in the power supply of television receivers and other equipments which have high output current requirements.
$14.95
Vacuum Tube - 5R4GY-A-B, Rectifier, Full Wave
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
Vacuum Tube - 117Z6GT, Dual Rectifier doubler
Full-wave rectifier designed for use in three-way portable receivers. Except for a common heater, the rectifier sections are separate, permitting the tube to be used as a full-wave or a half-wave rectifier, or as a voltage doubler.
$7.90
Vacuum Tube - 5Z4, Rectifier, Full Wave
The 5Z4 is designed for service as a power rectifier in AC operated receivers.
$8.90
Vacuum Tube - 5R4WGA-B-Y, Rectifier, Full Wave
Long life, ruggedized, reliable full wave rectifier tube.
$11.95
Vacuum Tube - 35Z3, Rectifier, Half Wave
New-Old-Stock (NOS) tube. The 35Z3 is a half-wave high-vacuum rectifier designed for use in a-c/d-c receivers. Electrically the 35Z3 is equivalent to the 35Z5GT except that the heater of the 35Z3 is not tapped for operation of a panel lamp. The 35Z3 is a loctal-based tube (compared to the octal base of the 35Z5GT.)
$5.90
Vacuum Tube - 6AX5GT, Rectifier, Full Wave
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
Vacuum Tube - 0Z4-A, Rectifier, Full Wave, Gas
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.
