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.
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.

Vacuum Tube - 117Z3, Half-wave rectifier, miniature type
Heater, for unipotential cathode. 117 volts AC-DC.
$4.90
Vacuum Tube - 5Z3, Rectifier, Full Wave
The 5Z3 is designed for service as a power rectifier in AC operated receivers which require high currents
$24.90
Vacuum Tube - 35Y4, Rectifier, Half Wave
Half-wave high-vacuum rectifier designed for use in a-c/d-c receivers. The heater is tapped to permit operation of a panel lamp.
$8.90
Vacuum Tube - 5Y4G, Rectifier, Full Wave
The 5Y4G is designed for use as a power rectifier in AC operated receivers.
$24.90
Vacuum Tube - 5V4GA, Rectifier, Full Wave
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
Vacuum Tube - 6BY5GA, Dual Rectifier
Full-wave vacuum rectifier for television damper service
$4.90
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 - 5U4GB / 5AS4A, Rectifier, Full Wave
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
$11.90
Vacuum Tube - 5AZ4, Rectifier, Full Wave
Filament-type high-vacuum full-wave rectifier designed for service in power supplies of moderate current requirements. The electrical characteristics of the 5AZ4 are equivalent to those of the 5Y3GT.
$6.90
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 - 25Z6GT, Dual Rectifier
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 - 83V, Rectifier, Full Wave
Power rectifier with low internal voltage drops. It is designed for service in AC operated receivers that require high currents
$25.60
Vacuum Tube - 5Y3G, Rectifier, Full Wave
Full-wave vacuum rectifier.

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 - 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 - 6CA4, Electro-Harmonix
Electro-Harmonix 6CA4 full-wave rectifier tube. Made in Russia.
$27.95
$34.90
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.
$3.90
Vacuum Tube - 7Y4, Rectifier, Full Wave
Heater type vacuum twin diode using the lock-in construction. It is intended for use as a full-wave rectifier in either AC or storage operated equipment where economy of heater power is desired.
$3.90
Vacuum Tube - 80, Rectifier, Full Wave, Tubular Glass
Filamentary full-wave high-vacuum rectifier designed for use in the power supply of a-c operated equipment
$29.90
