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 Jacket® converters have a one year warranty against manufacturer defects.

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.

These are the same thing but made but two different manufacturers.

Unfortunately, this is not an acceptable replacement for a 84 tube.

This is a solid state replacement for a tube rectifier and can be used in amps with a standby switch

A standby switch can be useful but it is not required.

This is not recommended for amplifiers without a standby switch. The rectifier tube or any replacements will not have any bearing on the bias settings.

Great solid state replacement rectifier! Have to put in a time delay relay to let power tubes warm up before high voltage is applied.

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

Beat regards,
