Matched pair of Premier 8 vacuum tube mono block amplifiers. Protective tube "cages" (never used) are included.
Less than 500 hours on original factory hand-selected matched tube set. The flagship of the conrad-johnson amplifier line for many years, the Premier Eight was a powerful 275 watts per mono-block making it the perfect choice for speaker systems which require tremendous power input and control. The Premier Eight used premium quality component parts throughout.
The power supplies, including the main storage reservoir, used only polypropylene and cjd polystyrene capacitors as opposed to the traditional deployment of electrolytic capacitors. The audio circuit consists of three stages. A triode- amplifier using four paralleled sections of two 5751s amplifies the input signal. That stage is direct-coupled to a cathode coupled phase inverter, each half of which consists of four paralleled sections of two high current twin triodes. The phase inverter circuit provides a balanced, low-impedance drive to the final output stage four pairs of 6550s.They operate in AB ultra-linear configuration, offering an optimal combination of high-power, low distortion, and low output impedance. All Premier Eights were supplied with a protective tube cover, especially important for households with small children and pets. 5-way binding post speaker connectors. Power Output 275 watts from 30Hz to 15kHz at no more than 1% THD or IMD into 4 ohms (also available connected for 2, 8 or 16 ohm loads). Response: 20Hz to 20kHz, +/.
