Main features of the amplifier
This power amplifier achieves dynamic output by using a single push-
pull 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.
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.
This amplifier employs a relay for signal switching to eliminate sound
loss, and discrete circuits for entire stages to optimize and upgrade
the circuits.
The terminals of this amplifier minimize sound quality deterioration.
Y-lugs and speaker wires can be tied securely.
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.
