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.

Yellow Jacket

Yellow Jacket converters allows amplifiers using common power tubes to use EL84s without modification or rebiasing.
Solid State Rectifier - Yellow Jacket® 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.
