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.
Combined high-mu triode and double diode using the 8 pin lock-in construction. It is designed for use as a diode detector, AVC rectifier, and an impedance or resistance coupled amplifier.
$4.75
Remote cut-off amplifier pentode designed for use as a radio-frequency or intermediate-frequency amplifier in a-c, a-c/d-c and auto receivers.
$19.95
Beam power amplifier tetrode designed for service in the output stage of a-c or battery-operated equipment. It is capable of supplying high-power output, power sensitivity, and efficiency with low percentages of third and higher order harmonics.
$9.90
Duplex-diode high-mu triode designed for use as a combined detector, automatic-volume-control rectifier and audio amplifier in a-c, a-c/d-c, or automobile receivers.
$16.90
Twin high-mu triode using the lock-in construction. It is designed for use as a voltage amplifier in resistance coupled cascade or phase inverter service.
$9.90
Twin triode designed for use as a grounded-grid radio-frequency amplifier or as a frequency converter at frequencies up to 300 megacycles.
$11.90
Sharp cut-off pentode voltage amplifier designed for use in television or other high-frequency amplifiers where the low impedance circuits required result in low gain which may be partially compensated for by use of a high transconductance tube.
$13.90
Semi-remote cutoff pentode using the lock in construction. IT is designed for use as an RF or IF amplifier.
$6.90
Combines two low-mu triodes in the lock-in construction. It is designed for use either as a phase inverter or as a voltage amplifier.
