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 by the major U.S. manufacturers, along with a small number of European manufacturers and are tested and guaranteed.
New Old Stock 6W5-G. Full-wave high-vacuum rectifier.
Also known by US military identifier VT-197A. The 5Y3GT is a filamentary twin-diode designed for full-wave rectifier operation in power supplies that have d-c output current requirements up to approximately 125 milliamperes. RCA brand.
New Old Stock (N.O.S.) tube. 25CD6GB is identical to the 6CD6GA except with different heater ratings. Beam power tube, octal base.
New Old-Stock (N.O.S.) tube. The 930 is a gas phototube sensitive to red through infrared light.
New Old-Stock (N.O.S.) tube. The 7189 is a power-amplifier pentode designed for use in the audio-frequency power output stage of television and radio receivers and high-fidelity amplifiers.
Metal, power-amplifier pentode primarily designed for use in the output stage of video amplifiers. The tube is capable of operating at high plate current levels and exhibits high transconductance and high power sensitivity.
Compact, quick heating thyratron designed for timing and control applications. It is xenon filled for quick starting and the ability to operate within very wide temperature limits.
High vacuum full wave rectifying tube.
Beam pentode designed for use as a series regulator in high-voltage power supplies.
Special quality tube designed for use as a wide band amplifier, cathode follower, series regulator tube for stabilized DC supply and output tube.
Beam-deflection tube for use in balanced-modulator, balanced mixer, and frequency-converter applications in single and double sideband, suppressed-carrier communication equipment operating at frequencies up to 100 Mc.
Novar type beam power tube used as a horizontal-deflection amplifier in color and black-and-white television receivers.
Beam power tube for horizontal-deflection-amplifier service in black-and-white TV receivers.
Semi-remote cutoff triode in the 7 pin miniature construction. It is designed for use as a VHF and RF amplifier at a B+ of 135 volts.
Neutrode triode tuner in the 7 pin miniature construction. It is designed for use in grounded cathode RF amplifiers, with the neutrode construction providing a lower grid to plate capacitance with consequent ease of neutralization.
Duplex-diode high-mu triode in which separate cathodes are provided for the diode and triode sections. The tube is primarily intended for service as a combined horizontal phase detector and reactance tube in television receivers.
Dual Tetrode, Power
Heater-cathode type transmitting beam power amplifier in the 9 pin miniature construction. It is intended for use in compact, low-power mobile transmitters and in the low-power stages of larger fixed station transmitters.
Twin diode miniature type intended for applications where dependable performance under shock and vibration is paramount. The 5726 is a "premium" version of the 6AL5W
Sharp cut-off tetrode designed for use as a radio-frequency or intermediate-frequency amplifier or as a detector tube in battery operated receivers.
Small, closely spaced, low-capacitance, high-vacuum diode designed for use through ultra-high frequencies. In measurement work, it is well suited to mounting in a probe and will maintain accuracy
Twin medium-mu triode whose sections are electrically independent except for the common heater. It is designed especially for use in equipment where the operating voltages are obtained from a 12 cell storage battery
