General

Triode 12AX7 is used to build the preamplifier, and triode 12AT7 is used to build inverter amplifier. In the power amplifier, fixed grid bias mode is adopted. Ultra-linear operating mode is adopted in the anode circuit, and KT 88 or 6550 or EL34 may be used for the electronic tube according to the user’s choice.

The amp features a reasonable design, well-chosen materials, high performance of the whole machine as well as high reliability. Protection is provided for the output transformer by the built-in single chip computer. Relay gating and volume regulation by potentiometer with ALPS motor are adopted for the actuating device of the remote controller, which is easy to use and meets HIFI principles. The remote controller is made of aluminum alloy, and all the buttons are made of stainless balls. Design is noble, elegant, pretty and in good taste. An aluminum radiator is used to remove the heat from the transformers, which provides both high reliability and nice appearance. The core of the output transformer is made of Z10 silicone steel sheets, and the windings are made by special technological process. It results in low distortion and wide frequency band.
