AM/FM Stereo Receiver (1976-78)
High sensitivity, outstanding circuit design in a new AM/FM receiver.
The Pioneer SX-1050 puts every significant AM/FM receiver feature together in a strikingly handsome package.
From a highly sensitive FM front end, a high selectivity IF section, to the low distortion, big power amplifier section that delivers the outstanding continuous power output of 120 watts per channel min RMS at 8 ohms from 20 to 20,000Hz, with no more than 0.1 % total harmonic distortion, the SX-1050 radiates the excellence that the stereo buff has come to expect from Pioneer electronics.
Such features as a phase locked loop IC in the MPX section, the audible multipath switch that helps eliminate FM wave interference, and the highly advanced equalizer section are not just extra touches in this receiver, but exemplify the considerable thought that has been applied to the overall design and circuit of the SX-1050.
Other important contributions to flawless sound include the Pioneer Twin Tone Control, the Toroidal-core transformer, the two very large capacitors in the power supply section - all calculated to reproduce the sound spectrum with stability arid full component protection in the inimitable Pioneer style.

mine is a 78 model. and still gives a good punch. bought it used 4 years ago. had it partialy rebuilt and cleaned. and i'm using it every day. so when we speak of longevity... and durability. whats more to say
