Main features of the amplifier Power amplifier utilizing single push-pull output This power amplifier achieves dynamic output by using a single pushpull amplifier. The power amplifying stage, which determines sound quality, consists of a single pair of transistors, successfully eliminating the emitter resistance used by conventional amplifiers to suppress overheating. The transistor output drives the speaker directly, reproducing sound with less undesired character. Frame beam base chassis (FBB chassis) A frame beam base chassis has been developed for the stereo amplifier. By combining a conventional frame beam chassis with a transformer base, providing high accuracy and stiffness, the frame is more stabilized, reproducing better sound with less overall distortion. A preamplifier constructed of completely discrete stages This amplifier employs a relay for signal switching to eliminate sound loss, and discrete circuits for entire stages to optimize and upgrade the circuits. Newly-designed large speaker terminals The terminals of this amplifier minimize sound quality deterioration. Y-lugs and speaker wires can be tied securely. You can connect banana plugs, too. The terminals can be used for bi-wiring connection, also, using both types of plugs mentioned above. Discrete amplifier for exclusive use with headphones This amplifier has a discrete amplifier used exclusively to drive headphones. The impedance can be switched among LOW, MID, or HI to match that of the headphones. 6US
