I have been unsuccessful in locating any information whatsover regarding this model. There is an upload for the 4DD-5 on this website unfortunately I am unable to post the link.

The 4DD-5 appears to be a later model since it uses IC's andt he 4DD-10 does not appear to use any.IC's.

According to the CD-4-A Chronology paragraph shown on hifimuseum.de the 4DD-10 was put on sale in March 1972 and in June 1972 the 4DD-5 was released. This is the only mention I have been able to find anywhere.

I am wondering if anyone might be able to assist with documentation for the 4DD-10.
