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.
Miniature sharp-cutoff pentode. Its high transconductance and low input and output capacitance adapt it to use as a wide-band amplifier or as a reactance tube.
$3.55
Low-voltage, low-current drain, battery type power pentode. It is designed for service with 90 volts of "B" battery and a single dry cell "A" battery.
$11.90
Triple grid variable MU amplifier. It is suitable for use with AVC in RF and IF amplifiers as it minimizes cross modulation
$6.90
Diode and a remote cutoff pentode with a common cathode of the 9 pin miniature type especially designed for use as combined IF amplifier and AM detector tubes in AM and AM/FM broadcast receivers.
$4.90
Pentode amplifier designed for application in power output stages of receivers
$27.90
Heater-cathode type pentode amplifier tube with remote cut-off characteristics and is designed for use as a radio frequency or intermediate frequency amplifier in a-c or battery operated equipment
$7.90
Power amplifier pentode designed for use in the audio-frequency power output stage of television and radio receivers and in high fidelity amplifiers.
$39.90
Heater-cathode type diode pentode tube designed for use as a detector and intermediate-frequency or audio-frequency amplifier. Except for heater rating the 6SF7 and 12SF7 are identical.
$6.90
Sharp cut-off amplifier pentode designed for use as a high-gain radio-frequency or intermediate-frequency amplifier. The 6SH7 is not recommended for use as a high-gain audio amplifier because undesirable hum may be encountered.
$4.90
Miniature pentode intended for use as a radio-frequency or intermediate frequency amplifier in automobile radio receivers. The tube is specially designed to operate with plate and screen voltages supplied directly from a 12-volt storage battery.
$3.90
The 41 is an indirectly heated cathode type power amplifier pentode designed for service in the output stages of AC, AC/DC and storage battery operated receivers.
$19.90
42 is a pentode amplifier designed for application in power output stages of receivers
Starting at $15.80
Subminiature pentode for use as an A.F. power amplifier in portable equipment.
$6.90
Triple grid general purpose detector amplifier. With the exception of capacitance, its electrical characteristics are identical with those of the 6J7G and 6J7GT.
$8.90
Combined triode and beam pentode especially intended for use in vertical output stage, particularly 110 degree picture tubes. Special attention has been paid to properties important for this application, such as microphonism and linearity.
$4.45
Single ended cathode type super control pentode primarily designed for amplifier service in radio or intermediate frequency circuits. In properly designed superheterodyne circuits it may also be used as a mixer tube.
$6.90
Miniature semi-remote-cutoff pentode designed primarily for use as an intermediate frequency amplifier in television receivers.
$5.90
Semi-remote cutoff pentode. It is designed for service in the IF stages of color and monochrome television receivers and may be used in the tuners of such sets as an AF amplifier.
$7.90
Triple grid sharp cut-off amplifier. It is designed for service in high gain RF and IF amplifier applications and for limited service in FM receivers. The double cathode connection is useful in reducing cathode circuit coupling.
Starting at $4.50
Sharp-cutoff pentode designed for use as a biased detector or high-gain amplifier.
$19.90
Pentode type amplifier tube with remote cutoff characteristics designed for use as a high frequency amplifier in radio receivers.
$6.90
Diode-audio pentode designed especially for service as a combined diode detector and pentode audio amplifier. The diode plate is located at the negative end of the filament.
$5.90
Miniature tube containing a high-mu triode and a sharp-cutoff pentode. The triode section is intended for service as a sync separator and the pentode section as a video amplifier.
$4.90
Double diode remote cut-off pentode for use as an R.F. or I.F. amplifier.
