About BAT REX 3 Tube Amplifier
REX 3 Tube Amplifier
“The world’s finest products offer a level of intimacy and involvement that sets them apart from the rest. That’s what the REX 3 delivers - a level of sonic intimacy that you won’t want to let go of if it grabs you. And you won’t find it anywhere else."
-Jeff Dorgay, Tone Audio
A truly different approach to tube amp design.
Think of REX 3 as four single-ended amplifiers in one box. Two waveforms per channel are summed at the output transformer. We call this a single-ended bridge design. This unique design achieves the finesse and naturalness of a Class A single-ended triode amplifier. With the power, dynamics, and control of a Class AB push pull amplifier.
Plug-and-play simplicity in a no-compromise design
The all-triode REX 3 represents a technological tour de force of modern engineering applied to traditional vacuum-tube power-amplifier design. From the plug-and-play simplicity provided by its auto-biasing and electronic protection circuits, to the palpable illusion of recreating the original musical event in your home, REX 3 combines high-power output, beautiful midrange texture, and superb extension at the frequency extremes.
Intelligent auto bias and electronic protection
REX 3’s advanced design eliminates the constant need to set and readjust the proper bias of the output tubes. An intelligent automatic-bias circuit adjusts for changing line voltage and aging tubes. For convenience, LED indicators show the status of each individual output tube. BAT further extends REX 3’s plug-and-play nature with a novel fuse-less protection circuit that eliminates the power-supply rail fuses to provide both a more refined sonic performance and user-friendly experience.
80 watts per channel (stereo) or 160 watts per channel (mono)
The all-triode REX 3 offers a robust 80 watts per channel in the stereo version or 160 watts per channel when used in monoblock configuration. Its 6C33C-B triode output tube offers many times the current delivery of the more common 6550 tube employed in traditional push-pull designs. High-impedance vacuum tubes like 6550 require far more complicated output transformers than the low-impedance 6C33C-B type. Consequently, REX 3 remains quite comfortable driving low-impedance loads.
25-years of refinement yields the greatest transparency ever heard in a BAT tube amp
Nothing was spared in the development of the REX 3 amplifier. It is unique among BAT tube amps for its use of an additional tube current source and Gen 3 SuperPak which delivers an even more palpable and textured sound with more top end extension than the already great VK90T.
Sonically, the result combines BAT’s hallmark naturalism with inimitable insight into musical textures, details, and expression.
New industrial design for improved performance
All REX 3 models replace the previous generation’s steel fabricated parts with a new all-aluminum chassis and improved venting patterns to maximize ventilation and thermal dissipation for long life and reliability of all tubes and critical components.
