The Pioneer electronics company has been in the audio business since 1938 when the company was started as a speaker repair shop in Tokyo. Since then, Pioneer has expanded to become one of the largest manufacturers of equipment for audio enthusiasts in the world. The SA-130 was an audio amplifier from this long-standing industry giant and featured many desirable features for an audiophile.
The physical dimensions of the Pioneer SA-130 are 420 millimetres in width, 95 millimetres in height, and 200 millimetres in depth. Its AC power input is 120 volts at 60Hz. The SA-130 is a 150 watt amplifier.
The front panel of the SA-130 featured a power switch, a headphone jack, and two toggles to turn two sets of speakers on and off. Three dials controlled the bass, treble, and balance of the audio output. Two more toggles turned on a "loudness" feature and the tape monitor. On the far-right of the front panel was a volume slider and three switches that allowed the active output to be set to phono, tuner, or auxiliary.
The back panel of the SA-130 featured audio inputs for three different analogue sources: phono, tuner, and auxiliary. There was also another input for tape with both recording and playback functions. Two more headphone jacks were installed on the back of the unit. Two sets of speaker contacts allowed for simultaneous output to two different sets of speakers. Finally, the back panel of the SA-130 featured three AC outlets and a port to install a grounding wire.
