About the SA-7500
The Pioneer SA-7500 is a two-channel, solid-state integrated stereo amplifier from the mid-1970s. It combines a preamplifier and power amplifier, with a separable pre-out/main-in arrangement, phono inputs for turntables, tuner and auxiliary inputs, two tape loops, microphone input, headphone output, and connections for two pairs of speakers. Its rated continuous output is 40 watts per channel into 8 ohms with both channels driven, across 20 Hz–20 kHz, at no more than 0.3% total harmonic distortion. This is the original SA-7500, not the later SA-7500 II.
