Record/playback only works when tape speed is set to 2.4cm

Everything seems to work just fine, albeit the audio sounds a bit wobbly, when the tape speed is set to 2.4cm. However, when i set the tape speed to 1.2cm, nothing works and only the battery light comes on.

Hi @isaakgilissen

Try replacing the drive belt.

Search online for Sony 3-377-420-11 to find suppliers that suit you best.

Also use some Isopropyl Alcohol 99%+ (available from electronics parts stores) to clean the capstan, pinch roller and the record, playback and erase heads in case they're creating a drag on the tape.

Here's the service manual that may help
