What's a Rectifier?
Every musical instrument amplifier has a rectifier. The rectifier converts the alternating current generated by the amp's power transformer into the direct current required by the amp's internal circuitry.
Originally, all amps used rectifier tubes. They gave amps a warm tone, but rectifier tubes are fragile and not very reliable. Many of the tubes are difficult to find, including the popular 5AR4 (or GZ34) used in the Fender Bassman, Tweed Twin, and Super Reverb, and the Marshall JTM 45. So most manufacturers switched to solid state rectifiers, but this resulted in a colder, hard sound.
What's a Reactive Rectifier™ ?
For our THD amplifiers, we wanted the reliability of a solid state rectifier with the warmth of a tube, so we created the THD Reactive Rectifier™ . Solid state rectifiers provide a uniform voltage drop, usually one to two volts, regardless of the load. The Reactive Rectifier™ "reacts" to the current load, providing the "sag" that made tube amps famous. It sounds like a tube rectifier, while sturdily surviving the punishment of a rock and roll environment.
How Do I Choose?
The RR5Y3 produces the most sag, the RR5U4 has a medium sag. The 5AR4 provides the least amount of sag, but still much more than you will get from any solid state rectifier.
If you want your amp to sound stock and you are replacing a tube rectifier, simply plug in the THD Reactive Rectifer™ with the same value. If you are replacing a solid state rectifer, or want a different tone from your amp, try the other models. With three options, you are sure to find the sound you want.
The THD Reactive Rectifier™ can be easily installed by any qualified technician. BE CAREFUL DONT DO IT IF YOU DONT KNOW WHAT YOUR DOING!
