Vacuum Tube - 6MJ6, Beam Power Pentode
Novar type beam power tube used as a horizontal-deflection amplifier in color and black-and-white television receivers.
Vacuum Tube - 6JT6A, Beam Power Amplifier
Beam power tube for horizontal-deflection-amplifier service in black-and-white TV receivers.
Vacuum Tube - 6FH5, Triode, HF
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.
Vacuum Tube - 6CN7, Dual Diode, Triode
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.
Vacuum Tube - 5763, Tetrode, Beam 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.
Vacuum Tube - 5726 / 6AL5W, Dual Diode
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
Vacuum Tube - 32, Tetrode
Sharp cut-off tetrode designed for use as a radio-frequency or intermediate-frequency amplifier or as a detector tube in battery operated receivers.
Vacuum Tube - 2-01C, Rectifier
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
Vacuum Tube - 12SG7, Pentode, Semi-Remote Cut-Off, JA
12SG7 - Pentode, Semi-Remote Cut-Off, JA
Vacuum Tube - 12JT6A, Beam Power Amplifier
The 12JT6A is the same as the 6JT6A except for heater characteristics and ratings.
Vacuum Tube - 7025, China
7025 - 9 pin miniature preamp tube Made in China Lower hum/noise version of a 12AX7/ECC83 Voltage gain rating: 1 2 3 4 5 6 7 8 9 10 Lows Mids Highs
Vacuum Tube - 3Q4, Pentode, Power
The type 3Q4 is a miniature type power-amplifier pentode designed for use in the output stage of battery operated equipment.
Vacuum Tube - 4-125A / 4D21, Tetrode, Power Amplifier
The 4D21 / 4-125A is a four-electrode tube designed for use as a power amplifier and oscillator. The anode is capable of dissipating 125 watts, and cooling is accomplished by radiation.
Vacuum Tube - 5654 / 6AK5W, Pentode, Sharp Cut-Off, RF
Miniature sharp-cutoff pentode for use as a wide-band, high-frequency amplifier. It is also useful in video and audio amplifiers, oscillators, mixers, frequency multipliers, and cathode followers.
Vacuum Tube - 5678, Pentode
Subminiature pentode for use as R.F, M.F., or A.F. amplifier, oscillator, self-oscillating mixer, A.M. detector etc.
Vacuum Tube - 5755 / 420A, Dual Triode
The 420A electron tube is a double-triode having separate indirectly heated cathodes. The heater is center-tapped to permit operation from a 6.3 or 12.6 volt filament supply.
Vacuum Tube - 6012, Tetrode, Thyratron
Isa negative control, xenon filled, four electrode thyratron designed for use in relay and grid-controlled rectifier applications. One type 6012 will carry 0.5 ampere in motor-control and in inverter service.
Vacuum Tube - 6689 / E83F, Pentode, Wide Band Amplifier
Special quality pentode designed for use in telephone equipment.
Vacuum Tube - 6AB7 / 1853, Pentode, Remote Cut-Off, RF
High transconductance semi-remote cut-off amplifier tube designed for television RF and IF amplifier service. Precautions should be taken not to exceed dissipation rating with expected line-voltage fluctuations, especially with fixed-bias operation.
