# 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.

Vacuum Tube - 6CA7 / EL34, Mullard, Pentode
Power pentode of the glass octal type. This tube is suitable for all applications which require peak powers of up to 11 watts from a single tube or up to 100 watts from two tubes in the normal push-pull arrangement.
$179.90 Out of Stock Vacuum Tube - 8SN7GTB, Dual Triode Medium-mu triode intended for use as a combined vertical oscillator and vertical deflection amplifier in 450 mA. series heater operated television receivers.$5.90
Vacuum Tube - 211 / VT-4C, Triode, Power Amplifier
New-Old-Stock (NOS) tube.
Also known by US military identifier VT-4C.
$399.90 Out of Stock Vacuum Tube - 4-125A / 4D21, Tetrode, Power Amplifier The 4D21 / 4-125A is a four-electrode tube designed for use as a power amplifier and oscillator. The anode is capable of dissipating 125 watts, and cooling is accomplished by radiation.$139.90
Vacuum Tube - 6060 / ECC801, Triode, Dual
Miniature type double triode employing the 9 pin glass button base, having the same general characteristics as the 12AT7 and as a frequency changer, opoerating at frequencies up to 500 Mc/s.

Vacuum Tube - 7308 / E188CC, Dual Triode
Special quality double triode designed for use as cascode amplifier, cathode follower, etc. in RF and AF circuits.
$99.90 Vacuum Tube - 6A3, Triode, Power Amplifier Filament type triode power amplifier designed for service in the output stage of audio amplifiers where high output and low harmonic distortion are desired. Its ratings and characteristics are similar to those of the 2A3 and 6B4G.$59.90
Out of Stock
Vacuum Tube - 6EM5, Beam Power Amplifier
High-vacuum, heater-cathode type of tube designed to indicate visually the effect of change in the controlling voltage. The tube is essentially a voltage indicator and as such is particularly useful to facilitate exact tuning of a radio receiver.
$6.95 Vacuum Tube - 7534 / E130L, Pentode Special quality tube designed for use as a wide band amplifier, cathode follower, series regulator tube for stabilized DC supply and output tube.$49.90

Vacuum Tube - 6HU6 / EM87, Indicator, Tuning
New-Old-Stock (NOS) tube. Tuning indicator tube
$26.95 Out of Stock$49.90
Vacuum Tube - 5751, JJ Electronics
A dual triode that can be used in place of most 12AX7 circuits. The rugged build of this tube and reduced gain (30% less than a 12AX7) can improve headroom and give better control in high gain stages allowing users to more easily dial in sweet spots. The JJ 5751 features a smooth and balanced tone and a detailed response with low noise and low microphonics.
$13.95 Vacuum Tube - E83CC Frame Grid, JJ Electronics Alternative to the 12AX7 or ECC83. The JJ Electronic E83CC is a high quality dual triode that rivals the NOS version of this tube. The E83CC was originally designed as an audio specific dual triode with very low noise and microphonics. The JJ E83CC stays true to the original design with the signature thick frame grid and boxed plate. The rigid frame allows for tighter tolerances and closer construction which results in lower noise and increased stability. The JJ Electronic E83CC is a great choice for high fidelity amplifiers as well as guitar amps and studio equipment. The E83CC has the same pinout and amplification factor as a standard 12AX7 and can be used in any 12AX7 or ECC83 position. Guitarist Description: This frame grid tube has an incredibly rich yet balanced tone. The E83CC works well for clean sounds but also breaks up with a satisfying warmth and plenty of articulation.$21.95
