About the REX 3 Power Amplifier
The Balanced Audio Technology (BAT) REX 3 Power Amplifier is a reference-class, fully balanced vacuum-tube power amplifier using an all-triode, transformer-coupled output stage. Its balanced bridge single-ended architecture uses zero global feedback and a short signal path. In stereo configuration it supplies 80 W per channel into either 8 or 4 ohms; it can be factory-configured or converted with a wire kit to operate as a 160 W monoblock into 8 or 4 ohms. BAT specifies custom output transformers with a 5 Hz–300 kHz bandwidth and an all-aluminum chassis with revised ventilation intended to improve heat dissipation, tube longevity, and reliability. The official BAT product page remains available, so it is treated as a current product rather than discontinued.
