NICORDER 750 TAPE / PHONOGRAPH
INFORMATION REFERENCE PAGE

     

This page is dedicated to one of the 'coolest', vintage reel to reel decks we have crossed paths with. A Nicorder model 750 Stereo Tape Recorder w/ built-in 4-Speed Phonograph, 'Transcription Tone Arm' and 8mm Film Synchronizer. It also features built-in Stereo-Tube Amplifier and matching Speakers. At this writing it also appears to have been associated with early Akai. Built by Nishikura Tape Recorder Co., LTD in Japan.

This page is dedicated to one of the 'coolest', vintage reel to reel decks we have crossed paths with. A Nicorder model 750 Stereo Tape Recorder w/ built-in 4-Speed Phonograph, 'Transcription Tone Arm' and 8mm Film Synchronizer. It also features built-in Stereo-Tube Amplifier and matching Speakers. At this writing it also appears to have been associated with early Akai. Built by Nishikura Tape Recorder Co., LTD in Japan. Circa...We are working on reconstructing the owners manual, brochure, specification sheet, and related paper work (they were damaged and the pages 'welded together' (appears to be with 'mouse pee'. yes we have to do some 'gross stuff' here). At some point we also hope to restore / refurbish / bring back to life the Nicorder model 750 reel to reel / phonographe / tube amplifier unit.
This appears to be from Circa 1961. This unit was likely purchased in Tokyo, Japan and brought over to America by a GI stationed there.
