Vacuum Tube - 6SH7GT, Pentode, Sharp Cut-Off, RF
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
Vacuum Tube - 10BQ5, Beam Power Amplifier, output pentode
The 10BQ5 is an output pentode designed for application in medium power hi-fi amplifiers. A pair of tubes in class AB, push-pull conventional operation yields an output of up to 17 watts at 4% distortion (without feedback).
$6.90
Vacuum Tube - 11MS8, Triode, Pentode
Miniature type used in combined vertical-deflection-oscillator and vertical-deflection-amplifier applications in black and white television receivers. Requires miniature 9-contact socket.
$9.90
Vacuum Tube - 12BL6, Pentode
Miniature remote-cutoff pentode intended for use as a radio-frequency or intermediate frequency amplifier in automobile radio receivers.
$3.90
Vacuum Tube - 12DQ7, Pentode, Sharp Cut-Off
Miniature power pentode primarily designed for use as the video output amplifier in television receivers. Features of the tube include high transconductance, low interelectrode capacitances, and high power sensitivity.
$6.90
Vacuum Tube - 1620, Pentode
Metal, sharp-cutoff pentode for use as a high-gain, audio-frequency amplifier or as a biased detector. The tube is a low-microphonic version of the 6J7 to which it is otherwise identical.
$12.90

Vacuum Tube - 25CD6G, Beam Pentode
New Old Stock (N.O.S.) tube. 25CD6GB is identical to the 6CD6GA except with different heater ratings. Beam power tube, octal base.
$8.05
Vacuum Tube - 26A6, Pentode
R-F amplifier pentode, miniature remote-cutoff type, for use with 12-cell storage battery supply.
$5.90
Vacuum Tube - 50BM8 / UCL82, Triode, Pentode, Power
Miniature type triode-pentode designed for use as an AF amplifier by triode section and AF power amplifier by pentode section in radio receivers.
$5.90
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.
