Nighthawk MK3.1

About the Nighthawk MK3.1

The Nighthawk MK3.1 is Raven Audio's entry-level Avian-series integrated tube amplifier, delivering 20 watts per channel from a push-pull ultralinear output stage using two matched pairs of 6L6GC power tubes. It employs a fully self-biasing tube circuit, so no user bias adjustment is required. The tube complement mirrors the Avian MK3 family and includes dedicated small-signal tubes for preamplifier, driver, and phase-inverter duties, contributing to the amp's rich, full, detailed, and highly engaging presentation that is often described as very "human" and palpable. The chassis provides five stereo RCA line-level inputs, 4 and 8 ohm speaker outputs, and a stereo RCA subwoofer/variable output, making it straightforward to integrate with a wide range of speaker systems and powered subs. Like other Avian MK3.1 models, the Nighthawk MK3.1 is built in the USA and is backed by a three-year parts and labor warranty from Raven Audio.
