Pioneer model SA-500
(1969 - 1972) 44 watt Solid State Integrated Amplifier
This is an efficient
medium-range pre/main amplifier built to very high specifications for this size
of unit. It has a set of controls, inputs and outputs for versatile operation
of speakers and tape recorders. Main amplifier total power is strong at 44 watts
at 4 ohms. Circuitry is all solid state and includes low-noise silicon
transistors. For those who want to enjoy full stereophonic realism the SA-500
is the set.
Features of the
SA-500
Excellent
Preamplifier Performance
The low-noise
silicon transistors are included in the preamplifier section and are vital for
the very best signal-to-noise ratio and distortion free sound. Distortion at 44
watts is less than 0,5% at 1kHz IHF
Truly precise Tone
Controls
Unlike most
amplifiers, in which tone control is only approximate, the SA-500 offers truly
acurate tone control through individual bass and treble. Signals really come
out as you want them.
Powerful Main
Amplifier
The main amplifier
section puts out 36 watts in music power at 8 ohms with distortion less than
0,5% at 1 kHz (IHF). That will give you room-shaking performance where and when
you want it. It has two sets of auxilliary inputs to make it a very versatile part
of your stereo system.
Exceptional
Flexibility
The SA-500 is fully
equipped with speaker outputs, tape recording/playback connector, loudness
contour and astereo headphone jack.

Would this make a good phono pre amp with my SA 8100? The phono inputs in the 8100 are shot.
