The Coincident Speaker Technology 211PP Dragon Mk II is a vacuum tube monoblock power amplifier rated at 75 watts per channel in triode, push-pull Class A operation. It uses a tube complement of one 6EM7 input/driver tube, one 300B driver tube, and two 211 directly heated triode output tubes per channel. The amplifier provides 8Ω and 16Ω output taps on high-purity 6N copper binding posts, has 1V input sensitivity, and 100 kΩ input impedance via unbalanced RCA inputs. Frequency response is specified as 20 Hz–20 kHz ±1 dB, with THD <1% at rated power and signal-to-noise ratio >90 dB. The Mk II revision incorporates dual power transformers for lower noise and cooler operation, an enlarged and significantly stiffened stainless-steel chassis with a high-gloss chrome/mirror finish for reduced resonance, and increased power-supply capacitance. The design employs high-quality interstage and output transformers and a massive high-voltage power supply that uses polypropylene capacitors in the signal-critical sections to avoid electrolytics. Each amplifier is meticulously hand-wired using Coincident's Statement-grade cabling, and many units include a high-quality discrete resistor volume potentiometer, allowing direct connection of a CD player or DAC without a separate linestage. Dimensions are approximately 11.5" W × 20.5" D × 10" H, and net weight is about 85 lbs (≈38.5 kg) per monoblock. AC mains are user-selectable 115V or 230V, 50/60 Hz, via an internal voltage-selection provision. The Dragon Mk II is widely noted in reviews for combining high power reserves with the tonal richness, transparency, dynamic expression, and extended yet airy treble typically associated with the finest directly heated triode amplifiers.
