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.
General purpose filament type triode designed for service in battery operated receivers. With the exception of capacitances, its ratings and characteristics are identical with those of the 1H4G.

Duodecar type used as horizontal-deflection amplifier in television receivers.
$39.90
Beam power amplifier designed primarily for use in the output stage of a-c/d-c receivers. It has high power sensitivity and high efficiency at relatively low plate and screen voltages.
$6.90
Miniature beam power amplifier especially designed for use in the power output stage of a-c/d-c receivers. Its small size and high efficiency make the tube especially useful where space limitation prevent the use of larger types.
$3.55
Miniature beam pentode primarily designed for use in the audio-frequency power output stage of radio receivers. Features include high power sensitivity and high efficiency at relatively low plate and screen voltages.
$15.90
Beam pentode primarily designed for use in the audio frequency power output stage of radio receivers. Features include high power sensitivity and high efficiency at relatively low plate and screen voltages.
$8.90
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
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
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
Heater-cathode type diode designed for use as a half-wave rectifier in ac/dc receivers. A heater tap is provided to permit operation with a panel lamp.
$23.90
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
Compactron beam-power pentode primarily designed for use as the horizontal-deflection amplifier in color television receivers. It is characterized by having a very low knee with a very high peak current of over an ampere.
$29.90
General purpose triode designed for service as an oscillator, detector, or amplifier.
$14.90
The 3A4 is designed for use in compact, lightweight, portable equipment. The relatively large filament employed in the 3A4 enables it to supply the high peak currents required in RF power applications.
$5.90
The 3A5 is intended for use in high frequency applications. The relatively large filament employed in the 3A5 enables it to supply the high peak currents required in RF power applications.
$5.90
Medium-mu triode - modulator, oscillator, amplifier.
