SA-73OO FEATURES

Powerful 35W + 35W Output

Hybrid IC circuitry employing dual positive and negative
power supplies is incorporated in the power amplifier
section. All stages are directly coupled in the OCL circuit
design to provide plenty of power at minimized distortion.
Output is 35W + 35W in the range of 2OHz~20kHz at 89
with both channels driven and 0.3% harmonic distortion.

Precision Designed Equalizer

The equalizer amplifier also utilizes a dual positive and
negative power supply and IC circuitry to assure RlAA
deviation within i0.3dB, while a maximum input of up to

200mV (at lkHz) can be easily handled (at 0.1% harmonic
distortion).

High Reliability Protector Circuit

Both relay and electronic circuitry combine to safeguard
valuable transistors and speakers in event of malfunction.
This special protector circuit also performs a muting func-
tion to prevent annoying surge noise when the POWER
switch is operated.

Specially Engineered Tone Controls

Advanced CR type tone controls and 2-stage direct coupled
amplifier provide highly effective control operation.
Regardless of the tone control settings, a flat frequency
response can always be obtained by employing the TONE
switch. This is convenient for checking cartridge and
speaker tone, and evaluating listening room characteristics.

Accept 2 Sets of Tape Decks

Recording and playback jacks are provided for two tape
decks, in addition to separate Tape Monitor switches.
Extremely convenient tape duplication and editing can be
performed if two tape decks are available.

Simple Styling Accents Performance Quality

The clean uncluttered front panel layout avoids a confusing
array of unnecessary controls and switches. Modern serene
styling is combined with one-glance operational ease.
