The Integrated Amplifier which adopted Power MOS
FET.
The simple three-step hardwired-connection DC power circuitry is
fundamentally adopted as the circuitry of a power amplifier part similarly to
HMA-9500.
The newly developed low noise integrated circuit is adopted as
an equalizer amplifier and tone amplifier, and circuitry serves as a 3 steps of
difference input hardwired-connection push pull output.
Moreover, an
interconnection of MC cartridge is possible by adopting the integrated circuit
of high gain.
The power-source part has realized the power-source part
which is generous also to a large swing by adoption of two power transformers
and smoothing capacitors (1000micro-F+1000micro F).
A low filter, the
tone-defeat switchpoint, the monitor switchpoint, the loudness, and the
loudspeaker circuit changing switch are carried.
