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.

$10.95
Vacuum Tube - 7G7 / 1232, Pentode
Sharp cut-off pentode voltage amplifier designed for use in television or other high-frequency amplifiers where the low impedance circuits required result in low gain which may be partially compensated for by use of a high transconductance tube.
$13.90
Vacuum Tube - 7Y4, Rectifier, Full Wave
Heater type vacuum twin diode using the lock-in construction. It is intended for use as a full-wave rectifier in either AC or storage operated equipment where economy of heater power is desired.
$3.90
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 - 10BQ5, Beam Power Amplifier, output pentode
The 10BQ5 is an output pentode designed for application in medium power hi-fi amplifiers. A pair of tubes in class AB, push-pull conventional operation yields an output of up to 17 watts at 4% distortion (without feedback).
$6.90
Vacuum Tube - 12SC7, Dual Triode, HI-MU
The type 12SC7 is a twin-triode amplifier designed for use as an audio amplifier or phase inverter. Special shielding arrangement in the base permits operation at a low hum level.
$5.90
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.
