Main features of the amplifier

Power amplifier utilizing single push-pull output
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.
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.

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.
