Pioneer SX-750 Stereo Receiver

Here we have a vintage Stereo Receiver from Japanese company Pioneer. The SX-750 is in fully working order and cosmetically the front panel is generally very good, but the wood effect on the casework is fair to poor. Please check our images. It will be suitably packaged and comes with manual, mains cable plus our usual three month warranty.
Pioneer Said….
The FM front end includes dual gate MOSFET and a high precision 4-ganged variable capacitor. The IF amplifier circuit employs a high integration density IC developed by Pioneer and three dual-element phase-linear ceramic filters to achieve a maximum of stability, Stable multiplex circuit operation is assured by the PLL IC design to which a newly developed type of negative feedback has been applied. This design provides low distortion with a high degree of reliability. In all important respects, including station drift, image rejection ratio, S/N ratio, capture ratio, and sensitivity, the crystal clear FM reception this tuner provides will satisfy the most discriminating taste.
The use of a first stage differential amplifier, and a pure complementary power amplifier allows high power output over a wide bandwidth to be obtained with a very low distortion rate.
Continuous power output of 50 watts per channel minimum RMS at 8 ohms from 20 Hz to 20 kHz with no more than 0.1% total harmonic distortion. The two 15,000 µF electrolytic capacitors in the power supply permit high sound quality even at lowest frequencies. By using a differential amplifier at the first stage input & impedance variations due to frequency are minimized, a Phono input capability of 200 mV with a distortion of 0.1% at 1 kHz is obtained. This, in combination with the careful selection of semiconductors used, holds RIAA deviation to within + 0.2 dB (30 Hz~15 kHz), You are assured of faithful reproduction of your records over a wide dynamic range with no discernible distortion.
The protection circuit and power relay are designed to instantaneously open the output circuit in the event of a short in the speaker leads or current surges which may occur without warning. This feature prevent, damage to speakers or transistors, and also prevents click noises during operation of the power switch.
Two sets of Tape terminals and the Duplicate switch permit one to selectively record from one tape to another when two tape decks are connected to the amplifier at the same time. It is thus possible to record onto a cassette from an open reel tape deck, or vice versa.
The large tuning scale provides more readable and hence more precise location of the desired frequency. The front panel has been designed for improved operating convenience.
