$19.60 Vacuum Tube - 6SG7GT, Pentode, Semi Remote Remote-cutoff pentode designed for use as a high-gain radio or intermediate-frequency amplifier. Features of the tube include high transconductance, low grid-plate capacitance, and a dual cathode connection$6.90
Vacuum Tube - 6SS7, Pentode, Remote Cut-Off
The 6SS7 is an RF pentode which as remote plate current cutoff. It is suitable for operating with AVC in Rf and IF amplifiers. The use of this tube will reduce cross modulation effects.
$6.90 Vacuum Tube - 6T9, Triode, Pentode Duodecar type tube used in audio-frequency circuits. The triode unit is used as a voltage amplifier; the pentode unit is used as a power amplifier.$19.90
Vacuum Tube - 6U7G, Pentode, Remote Cut-Off
Triple grid remote cut-off amplifier. It is suitable for use with AVC in RF and IF amplifiers and minimizes cross modulation. Its electrical characteristics are similar to those of the 6D6.
$9.90 Vacuum Tube - 717A, Pentode High-frequency pentode.$22.90
Vacuum Tube - 7408 / 6V6GT, Beam Power Amplifier
Beam power pentode primarily designed for use in audio frequency power amplifier applications. The tube is a direct replacement for the 6V6Gt, but features additional controlled zero-bias characteristics.
$79.90 Vacuum Tube - 7558, Beam Power Amplifier Beam pentode designed for use as a class "C" RF amplifier, oscillator, or frequency multiplier up to 175 Mc. It can also be used as a modulator or AF amplifier. Type 7558 is designed for fixed station equipment.$14.90
Vacuum Tube - 7581A / KT66, Beam Power Amplifier
Beam-power pentode primarily designed for use in audio-frequency power-amplifier applications. The 7581A is unilaterally interchangeable with the 7581 and the 6L6GC.
$99.90 Vacuum Tube - 7695, Beam Power Amplifier Beam power pentode featuring a remarkably high power sensitivity as an audio power amplifier. In Class A1 operation, it can deliver 4.5 watts of power with a B+ voltage of only 130 volts.$5.90
