Notes: The unit powers on and appears to be functioning but I have not been able to test the recording capabilities with blank cassette tapes. All the tapes I have already have content on them so the master will record but when I place the cassettes with content in the duplicator slots the stand by light will come on but it will not record to the cassettes. Includes power cord. Please see photos for full condition. Sold as is. The Hamilton Cassette Duplicator Model HA-340/PA-340 is a 1 to 3 vintage cassette duplicator manufactured by the brand Hamilton or HamiltonBuhl. This unit, made in China and is designed to duplicate cassette tapes. With its unique features and retro design, this cassette duplicator is perfect for collectors of vintage audio and video equipment.
