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 - 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 - 35B5, Tetrode, Beam Power
Miniature beam power amplifier especially designed for use in the power output stage of a-c/d-c receivers. Its small size and high efficiency make the tube especially useful where space limitation prevent the use of larger types.
$3.55
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 - EL509, JJ Electronics
The JJ Electronic EL509S is an eight pin octal based version of the EL509 / EL519. This modified version does not have the top plate cap which is instead wired to a pin on the octal base. This tube is rated for 700V and 42 Watts plate dissipation. The JJ EL509 is popularly used in output transformerless OTL amplifiers.
