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.
Converter tube designed for stable operation over an extended frequency range. It consists of a heptode mixer and a triode oscillator, having a common cathode. The injector grid of the heptode is internally connected to the triode grid.

$16.90
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
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.
$15.90
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 30.
$15.90
Heater-cathode type triode designed for use as a detector, amplifier, or oscillator tube in a-c or battery operated equipment.
$15.90
Medium mu triode and a sharp cutoff pentode. The pentode section may be used as an IF amplifier or a reactance tube; the triode section is well suited for use in low-frequency-oscillator, sync clipper, sync separator, and phase splitter circuits.
$15.90
Miniature high-mu twin triode having separate cathodes. It is designed for service as a relay-control tube in remote tuning units of television receivers.
$15.90
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.
$15.90
Three-electrode general purpose tube of the heater-cathode type for use as an amplifier and detector in a-c receivers.
$15.25
Miniature medium-mu twin triode suitable for a wide variety of general-purpose amplifier, oscillator, and multivibrator applications.
