This beautiful component is Miura-san's first foray into 300B tube amp production under the Air Tight logo. With the same approach to straightforward circuit design and layout and meticulous construction standards as his other offerings, the ATM-300 brings the magic of the legendary 300B triode tube to a new level of musicality. Using a single 300B per channel, the amp delivers 8 Watts per side of Class A triode purity (obviously, proper 'speaker selection is critical). Key to the superb performance is Mr. Miura's choice of the Tamura transformers for output power, making for stable, fuss-free operation (the unit is even self-biasing, although a handy bias-current meter lets you check up on the state of the tubes while playing). The amp also offers a 3-position (0dB, 4dB, 6dB) "damping control" to optimize negative feedback. The unit comes complete with WE 300B
