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.
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.

Miniature pentagrid-converter designed for use as a combined mixer and oscillator in superheterodyne circuits. Because of its small size and high operating efficiency, the 1R5 is especially adapted for compact, battery-operated equipment.
$5.90
Miniature type triode-pentode designed for use as an AF amplifier by triode section and AF power amplifier by pentode section in radio receivers.
$5.90
Compactron device containing two sharp cutoff pentodes, designed primarily for intermediate-frequency amplifier service in television receivers.
$5.90
Medium-mu triode intended for use as a combined vertical oscillator and vertical deflection amplifier in 450 mA. series heater operated television receivers.
$5.90
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
Cathode type high mu triode designed for use in high gain resistance coupled circuits. A lower amplification factor enables the use of a large signal input both under 250 volt and 100 volt operating conditions.
$5.90
Beam power tube of the 9-pin miniature type designed for use as the output amplifier in automobile radio receivers operating from a 12-volt storage battery. The 12AB5 can provide high power output.
$5.90
Beam power pentode primarily intended for use as an audio frequency power amplifier. It is particularly useful in applications where the available supply voltage is relatively low.
$5.90
Variable-mu pentode amplifier in the octal glass construction. It is suitable for use with AVC in RF and IF amplifier and minimizes cross modulation.
$5.90
Mixer tube designed for service with a separate oscillator as the first detector in superheterodyne receivers. The control grid is of the remote cut-off type which allows the use of AVC and minimizes cross-modulation.
$5.90
Duplex-diode high-mu triode intended primarily for use as a combined detector, amplifier, and automatic-volume-control tube in radio receivers. The triode section incorporates a high amplification factor

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
The 6K7GT is an indirectly heated pentode of the vari-mu (remote cut-off) type for use in the RF or IF stages of radio equipment.
$5.90
Pentode voltage amplifier using the lock-in construction. It is designed for RF or IF service in AC/DC receivers.
$5.90
Miniature semi-remote-cutoff pentode designed primarily for use as an intermediate frequency amplifier in television receivers.
$5.90
Half-wave rectifier in the 7 pin miniature construction. Features of the tube are a 100mA. heater with 20 second warm-up time.
$5.90
Combines two diodes and a high-mu triode using a common cathode. It is designed for service as a diode detector, AVC rectifier, and as a high gain resistance coupled amplifier in AC, storage battery, and AC - DC operated receivers.
