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.

This is perfect for my new 45 amplifier to replace "5U4", that was making lousy/annoying hum noise. I love this YJR!

Beat regards,

Using a solid state rectifier will stiffen up your power supply a bit and reduce sag.

As long as you are replacing a 5AR4/GZ34, 5U4 or 5Y3 rectifier tube then this will work. It may have more pins that your tube but the extra pins are not connected to anything.
