Sony ES Series Amplifier

For sale is the legendary Sony TA-F690ES amplifier. It's in perfect visual and technical condition, as seen in the photos. The amplifier has undergone a comprehensive cleaning (including switches, potentiometers, and sockets), and the main potentiometer, selector switch, and "Source Direct" have been replaced. It's ready for many years of continued use.
No remote controller!
