# 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.

#### Ruby

Ruby tubes are manufactured in China and tested for quality and performance.

#### 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.

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 - 7B6, Dual Diode, Triode Combined high-mu triode and double diode using the 8 pin lock-in construction. It is designed for use as a diode detector, AVC rectifier, and an impedance or resistance coupled amplifier.$4.75
Vacuum Tube - 5670 / 2C51W, Triode, Dual
Miniature medium-mu twin triode each section of which as a separate cathode connection. The tube is suited for use in a wide variety of general-purpose amplifier and mixer circuits as well as numerous multi-vibrator and oscillator applications.
$4.90 Vacuum Tube - 5749 / 6BA6W, Pentode, Remote Cut-Off Miniature remote-cutoff pentode intended for use as a high-gain radio frequency or intermediate-frequency amplifier. Its remote-cutoff characteristic makes it suitable for use in circuits to which it is desired to apply automatic-gain-control.$4.90
Vacuum Tube - 6AK6, Pentode
Heater-cathode type of tube intended for use in compact, light-weight equipment. Because of its small size, the 6AK6 can be used singly or in push-pull to effect a more compact design of power-line receivers.
$4.90 Vacuum Tube - 6AL5 / 6EB5, Dual Diode The 6AL5 combines two independent diode units in the 7 pin miniature construction. Its high perveance permits high efficiency in either FM or AM detector service.$4.90
Vacuum Tube - 6AW8A, Triode, Pentode
Miniature tube containing a high-mu triode and a sharp-cutoff pentode. The triode section is intended for service as a sync separator and the pentode section as a video amplifier.
$4.90 Vacuum Tube - 6H6, Diode, Twin Twin-diode with individual cathodes brought out to separate base pins. The 6H6 is designed for service as a diode detector, automatic volume control rectifier, or as a low current power rectifier$4.90
Vacuum Tube - 6SF5, Triode
Heater-cathode type high-mu triode designed for service as a high gain audio-frequency amplifier and is especially useful in resistance-coupled amplifier circuits in a-c or battery operated equipment
$4.90 Vacuum Tube - 6SH7, Pentode, Sharp Cut-Off, RF Sharp cut-off amplifier pentode designed for use as a high-gain radio-frequency or intermediate-frequency amplifier. The 6SH7 is not recommended for use as a high-gain audio amplifier because undesirable hum may be encountered.$4.90
Vacuum Tube - 6AK5 / EF95, Pentode, Sharp Cut-Off
Miniature types used as rf or if amplifiers especially in high-frequency wide-band applications at frequencies up to 400MHz.
$4.90 Vacuum Tube - 117Z3, Half-wave rectifier, miniature type Heater, for unipotential cathode. 117 volts AC-DC.$4.90
Vacuum Tube - 12A4, Triode, Medium-MU
