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.
New Old Stock (NOS)
Our new-old-stock tubes were made in the U.S. by the major manufacturers, with several types made in Western Europe or Japan. All NOS tubes are tested and guaranteed.
The 841 is an RF power amplifier, oscillator, and AF voltage amplifier.

$29.90
Beam power pentode primarily designed for use in audio-frequency power amplifier applications. Features include high power output capabilities, high plate and screen dissipation ratings, high efficiency, high power sensitivity, and low distortion.
$66.95
Combines two diodes and a high-mu triode, using a common cathode. It is designed for service as a diode detector, AVC rectifier, and as a high gain resistance coupled amplifier in AC, storage battery, and AC - DC operated receivers.
$15.90
Miniature remote-cutoff pentode intended for use as a radio-frequency or intermediate frequency amplifier in automobile radio receivers.
$3.90
Miniature high-mu twin triode each section of which has an individual cathode connection - especially suited for use in resistance-coupled voltage amplifiers, phase inverters, multivibrators, and industrial-control circuits.

New-Old-Stock (NOS) tube. The 35Z3 is a half-wave high-vacuum rectifier designed for use in a-c/d-c receivers. Electrically the 35Z3 is equivalent to the 35Z5GT except that the heater of the 35Z3 is not tapped for operation of a panel lamp. The 35Z3 is a loctal-based tube (compared to the octal base of the 35Z5GT.)
$5.90
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.
