About the Mark III
The Dynaco Mark III is a classic tube monaural power amplifier kit delivering 60 watts RMS output with a frequency response of 20 Hz to 20 kHz and total harmonic distortion around 0.5% to 1%. It uses a push-pull design with two KT88 or 6550 output tubes, a 6AN8 input tube, and a GZ34 rectifier tube. The amplifier is highly regarded for its natural, clean sound with low distortion and excellent transient response, making it suitable for demanding audiophiles. It features a sturdy steel chassis, high-quality output transformers, and a well-designed power supply with a Dynakit C-354 filter choke. The amplifier is designed for 4, 8, and 16 ohm speaker loads and includes traditional bias adjustment controls. The Mark III is a kit requiring assembly but is praised for its straightforward construction and upgrade potential. Modern versions use premium components such as Cornell Dubilier capacitors and carbon film resistors for improved reliability and sonic performance. Despite its vintage design, it remains a highly respected amplifier for tube audio enthusiasts.
