# 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 Jackets

Yellow Jackets allows amplifiers using common power tubes to use EL84s without modification or rebiasing.

TAD is a German company established in 1993 which selects and matches electronic tubes and manufactures musical instrument accessories.

#### 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.
