Description
Produced in the early 60s, this tape recorder looks to be another variation on the theme of a US company contacting Denon in Japan to make a branded tape recorder slightly different than the Denon 700 . Freeman electronics, another short-lived US brand had a very similar tape recorder that was not as sophisticated in the preamplifier section. But the transport looks very similar.
The preamplifier was model GB-625 and looked pretty advanced for its time.
Perhaps this was not intended as a consumer tape recorder
