A Sony model, bought in Japan. Quality item which I used to record telephone interviews (with consent of course). Has a standard 3.5mm input plug to plug into your recording device. At the other end it plugs into your telephone and has a socket into which your usual cable from the telephone socket to the telephone is inserted.
Note that this is for use with a telephone with a curly wire, not a cordless phone. It does not record automatically. You must choose when to begin recording on your own recording device. It is therefore ideal for pre-planned telephone calls such as interviews, business meetings etc where it has been agreed to make a recording.
Photo on the next post. If you need a sony walkman cassette recorder with spare tapes for a complete set-up, just add £5 (the old-fashioned way of recording!)
