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 - E34L, JJ Electronics, Blue Glass
Blue glass envelope. The JJ Electronic E34L adds more power to a standard EL34 due to its higher grid voltage rating. This increase gives the tube more headroom and a tighter response on the low end. The wide frequency response of this tube offers excellent harmonics that work in a variety of genres ranging from the cleanest cleans to rich and aggressive breakup.
Starting at $30.69
Vacuum Tube - KT66, Genalex Gold Lion
Super Premium power beam tetrode & exact copy of the original clear glass KT66, used in the early Marshall amps which created Eric Clapton’s "Bluesbreaker" Tone.” Full sound with improved bass response and shimmering top-end.
  • Originally a British equivalent to 6L6 and a mainstay of the British hi-fi industry
  • Used in 50s - 60s hi-fi favorites such as the Heath W-5M and many Leak amplifiers
Starting at $67.35
Vacuum Tube - 12SG7, Pentode, Semi-Remote Cut-Off
Semi-remote cut off pentode voltage amplifier in the octal metal construction. It features high transconductance with low grid-plate capacitance and a dual cathode connection to minimize effects of common cathode circuit coupling.
$5.35
Vacuum Tube - 25L6, Beam Power Amplifier, Metal
Power-amplifier tube of the all-metal type for use in the output stage of transformerless (ac/dc) radio receivers, especially those designed to have ample reserve of power-delivering bilities.

$6.90
Vacuum Tube - 6H6GT, Dual Diode
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 - 6SB7-Y, Pentagrid Converter
Pentagrid metal tube designed for use as a combined mixer and oscillator in superheterodyne circuits. Especially useful in FM receiver service below 120 megacycles.
$6.65
Vacuum Tube - 7025, Triode, Dual, High MU
Miniature, high-mu, twin triode primarily designed for use in low-level stages of high-gain audio-frequency amplifiers. Use of the 7025 in this application is advantageous because of its low hum output.
$59.95
