Description

Manufactured by Nippon Columbia, the Denon DH-710 was also offered with two other variations. Denon DH-710 F & Denon DH-710 S
This was a semiprofessional deck that separated the record/playback electronics from the transport, bearing some similarity to the Teac A-7300 variations. The 710 was a complete machine or available with separate record/pb electronics in the F and S configurations.
A full half track recorder with a quarter track playback head, this machine was very versatile. It became the chosen machine for the legendary audio designer, Tim De Paravicini to modify. We don’t know if he simply upgraded the original record and playback amplifiers with higher end components or if it was a complete redesign. The 710F was very common in Japanese radio stations and recording studios. A remarkable achievement for a company that produced relatively few R-R paper corridors
A stranger to the North American market, it appears that the 710’s were only available in Japan and priced at ¥348,000 in 1974.
These seem to be readily available on the used market if you can figure out a way to navigate Yahoo Japan website. At 61 pounds shipping would be expensive needless to say. A step down transformer would get you to the 100 volt power requirement.
