⭕ 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. The Premier Eight-A added a noise filter to the bias indicator circuit, upgraded resistors and capacitors in the voltage amplifier and bias power supplies, and improved input wiring. The Premier Eight-XS is a an Eight-A with output stage configured to use EL34s connected for triode operation. Premier Eight comes supplied with a protective tube cover, especially important for households with small children and pets. Excellent cosmetic shpae, everything works as it should.
