SONY Walkman Cassette Player WM-EX677 Operation confirmed

This is a Sony cassette player. As it has been stored at home, there are some minor scuffs and marks on the surface. To ensure proper cassette playback, the following maintenance was performed:

・Replaced with a high-quality rubber belt

・Cleaned the head and pinch roller

・Applied contact cleaner to electrical contacts

・Cleaned the circuit board

・Cleaned the gears and internal components

Although maintenance was performed, the player could not be operated using a gum-stick battery due to rust on the battery terminals.

However, I confirmed that all standard functions—such as playback, fast-forward, and rewind—work correctly when using the AA battery case. There is no significant wow or flutter, so music playback should be normal.

Please note that a separate AA battery is required for operation.
