Reference 650FET R by Quadraflex Stereo Receiver

The item is a vintage stereo receiver, specifically identified as a 'Reference: 650FET R by Quadraflex'. It features a rectangular, horizontally oriented form factor, characteristic of audio components from the 1970s or early 1980s. The outer casing appears to be made of black metal or a similar dark-colored composite material. The front panel, which is the most visible part, has a matte black finish with various controls and display elements. Notable features include a large, smoked glass or plastic display window at the top, which appears to cover a tuning dial or digital display, though the specifics are unclear due to reflections and the angle. Below this window, the model name 'Reference: 650FET R' is prominently displayed in a gold-orange hue, with 'by Quadraflex' in a lighter blue-green font. The lower section of the front panel is populated with numerous controls: several black rotary knobs of varying sizes, push-button switches, and toggle switches. Specifically, there's a large knob labeled 'PHONO 1', 'PHONO 2', 'TAPE 1', 'TAPE 2' and 'FM/AM', indicating input selection. Further to the right, there are toggle switches for 'SUBSONIC', 'TAPE MON 1', 'TAPE MON 2', and 'MODE', along with more rotary controls for 'LOUDNESS', 'TURNOVER', 'BASS', and 'TREBLE'. The overall construction suggests a robust build quality typical of audio equipment from its era. The item exhibits some visible wear and tear consistent with its age, including what appear to be light scratches or scuff marks on the display window. The front panel itself seems generally clean but may have minor dust or surface imperfections not clearly discernible. There are no obvious signs of major damage or repairs from this view. The visible wiring suggests it is connected to a power source or other audio components. Its style period is firmly rooted in the vintage hi-fi aesthetic, characterized by a functional layout and a focus on tactile controls. The 'FET' designation in the model name suggests the use of Field-Effect Transistors in its amplification stages, a quality indicator for certain audiophiles.
