Sony - TA-F411R - ST-S310 Hi-fi set - Multiple models

Sony TA F 411R amplifier and tuner ST S 310.
The system comes from a household liquidation and was tested.
Everything plays well, only with the tuner I did not notice stereo imaging.
Maybe it's just the antenna since I only tried with a piece of cable.
There might also be a remote control, but unfortunately the batteries have leaked and would need cleaning.
A defective CD player would be included as a freebie; it always shows 'No Disk' and has nothing to do with the auction, just a somewhat heavier package.
Remote control and control cable are included; the remote's batteries have leaked and corroded.
Please examine the pictures carefully and read the text closely so there are no misunderstandings later.
