# 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.

#### Solid State Replacements

Solid state replacements for vacuum tubes are great for use for hard to find or costly vacuum tubes and for reducing 'sag' in power supply applications.
Solid State Rectifier - Yellow Jackets® YJR, For 5AR4, 5U4, 5Y3
The YJR is a direct plug-in replacement adapter for use in most amplifiers that use 5AR4/GZ34, 5U4, 5Y3 or similar full-wave rectifier tubes. The YJR converts your amp's vacuum tube rectifier to a solid state rectifier, reducing tube sag for a tighter sound and feel. The tube rectifier can easily be swapped back in when sag is desired. This Yellow Jacket® is a solid state device and as such does not come with vacuum tubes.
• Converts most audio amplifiers which use a vacuum tube rectifier 5AR4/GZ34, 5U4 or 5Y3 to a solid state device.
• Safe for all common amplifiers and transformers.

All Yellow Jackets® have a one year warranty against manufacturer defects.

$2.95 Save 50% Originally:$5.90
Vacuum Tube - 6CA7, JJ Electronics
A true to form reproduction of a classic tube that will work in most EL34 amps. The 6CA7 is often considered the American cousin to the British EL34. Sonically, this tube is closer to a 6L6 than an EL34 but without the sometimes harsh high end of the 6L6.
Starting at $16.45 Vacuum Tube - 6CS6 / EH90, Heptode Miniature dual control pentagrid tube intended for use in sync separator circuits. In these circuits it provides improved noise immunity. Both control grids have sharp cut-off characteristics.$2.45

Originally: $4.90 Vacuum Tube - 6J8G, Triode, Heptode Converter tube designed for stable operation over an extended frequency range. It consists of a heptode mixer and a triode oscillator, having a common cathode. The injector grid of the heptode is internally connected to the triode grid.$18.90
Vacuum Tube - 6L6GC, JJ Electronics
The JJ Electronic 6L6GC is the classic pentode built with the rugged construction that only JJ could deliver. At 30W, this tube delivers plenty of headroom. The highs are clear and responsive with warm mids and tight solid lows. Known for their reliability and articulation, the JJ 6L6GC is a great option guitar amplifiers and Hi-Fi stereo equipment.
Starting at $18.25 Vacuum Tube - 6L7, Heptode Mixer tube designed for service with a separate oscillator as the first detector in superheterodyne receivers. The control grid is of the remote cut-off type which allows the use of AVC and minimizes cross-modulation.$5.90
Vacuum Tube - 6SA7, Heptode
Metal pentagrid converter. It is intended to perform the combined functions of the mixer and oscillator in superheterodyne receivers, especially those of the all-wave type. The 6SA7 is constructed to provide excellent frequency stability.
$3.90 Vacuum Tube - 6V6, JJ Electronics This 6V6 has the standard rugged construction we’ve come to expect from JJ which allows it handle much higher plate voltages than the typical 6V6 tube.
