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.

Originally: $12.90
High-vacuum rectifier intended for use as a full-power rectifier in television receivers.
$8.90
The 5T4 is designed for service as a power rectifier in AC operated receivers.
$19.95
Filamentary full-wave high-vacuum rectifier designed for use in the power supply of a-c operated equipment
Starting at $17.60
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
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
The 5U4G is designed for service as a power rectifier in AC operated receivers which require high currents
$49.90
Heater, for unipotential cathode. 117 volts AC-DC.
$4.90
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 5Z4 is designed for service as a power rectifier in AC operated receivers.
$8.90
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
The 5Z3 is designed for service as a power rectifier in AC operated receivers which require high currents
$24.90
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
Heater-cathode type power rectifier in the miniature construction. Its low voltage drop and small size adapt it to use with vibrator-type inverters in automobile receivers.
$7.90
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
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
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
Miniature half-wave rectifier for use in line-operated equipment having series-connected heaters. The heater is tapped to permit operation of a panel lamp.
$7.90
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
Filamentary full-wave high-vacuum rectifier designed for use in the power supply of a-c operated equipment
