# 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.

#### New Old Stock (NOS)

Our new-old-stock tubes were made by the major U.S. manufacturers, along with a small number of European manufacturers and are tested and guaranteed.

#### Yellow Jackets

Yellow Jackets allows amplifiers using common power tubes to use EL84s without modification or rebiasing.
Vacuum Tube - 6AU6A / EF94, Pentode, Sharp Cut-Off
Miniature sharp cutoff pentode primarily designed for use as a high-gain radio-frequency or intermediate-frequency amplifier. Its low grid-plate capacitance and high transconductance make it especially suited for high-frequency wide-band applications
$7.90 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.$14.95
