The Pioneer SX-750 is a classic AM/FM stereo Pioneer receiver. In its heyday (introduced in 1976 and made through 1977), it was an upper mid-range receiver that offered excellent features and performance to match. Moreover, it wasn’t and still isn’t expensive. In this article, we will be doing a review of the Pioneer SX-750 AM/FM Stereo Receiver.

Power and Impedance

The SX750 comes with an inbuilt pre-amplifier, power amplifier, and tuner sections. These allow the receiver the advantage of pushing additional power for your audio system. 

The receiver pushed out 50 watts per channel at 0.1% total harmonic distortion. This is the continuous power output of 50 watts per channel at a minimum.

In terms of impedance, the receiver is rated at 8 ohms, from 20 to 20,000 Hz with no more than 0,1% Total Harmonic Distortion.

Sound Quality

There are some unique characteristics of the SX-750 that makes it a cool-sounding receiver. 

Firstly, all the input/output terminals and circuits of the pre-amplifier/tuner sections are laid out on one large printed circuit board. This eliminates shielded input cords which enhances overall tonal quality.

In addition, the receiver offers extra sensitivity and selectivity by means of the dual-gate MOS type FET and a 4-gang variable capacitor.

Finally, IF section uses up-to-the-minute circuits and differential amplifier ICs which ensures a high signal/noise ratio and low distortion.

Audio FM and AM Tuning

The receiver also offers FM and AM tuning capabilities. This is enabled by a dual gate MOS type FET and a 4 gang variable capacitor. 

Build Quality

The SX-750 has a strudy build, which is characteristic of Pioneer receivers. The metal and/or wooden finish make it very durable as well as easy to clean and maintain.
