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.
Sharp-cutoff pentode designed for use as a biased detector or high-gain amplifier.
$19.90

The 6K6GT is an indirectly heated cathode type power amplifier pentode designed for service in the output stages of AC, AC/DC and storage battery operated receivers.
$11.90
Sharp cut-off general purpose amplifier. With the exception of heater and capacitance ratings, the electrical characteristics are similar to those of the 6C6.
$11.90
Low-voltage, low-current drain, battery type power pentode. It is designed for service with 90 volts of "B" battery and a single dry cell "A" battery.
$11.90
Medium mu triode and sharp cutoff pentode in the 9 pin miniature construction. It is intended for use as a combined VHF oscillator and mixer in television receivers.
$9.90
Miniature sharp-cutoff pentode designed primarily for use as a high gain radio-frequency or intermediate-frequency amplifier. Low grid-plate capacitance and high transconductance make it especially suited for high-frequency wide-band applications.
$9.90
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
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
Pentode power amplifier using the miniature construction. It is intended for service in AC and storage battery operated receivers where moderate power sensitivity and power output is desired.
