TRANSISTOR RADIO DESIGN

This Hi-Delity 6T-330 was manufactured in Japan by Constant. Constant was a brand name used by Fuji High Frequency Radio Lab, Co, Ltd. This company may have been a subsidiary of Fuji Electric Industry Co, Ltd founded in 1923.

Constant designed and manufactured some highly collectible and unusual transistor radios. Constant also made radios under the brand names Vulcan, Windsor, Barlow, Minute Man, Supre-Macy, Personna, Morse, Crestline, AFCO, Fuji, Sabre and probably others. Other than that I know very little about Constant.
 

This Hi-Delity features a reverse-painted tuning dial behind clear plastic. The white plastic behind the tuning dial is lightly corrugated. The red volume knob stands out nicely against the black plastic cabinet.

It can also be found branded as an  Imperial, Crestline, Morse and Jupiter, all with the same model number of 6T-330. There is also a Supre-Macy 6T-330 that has a mostly under-painted face with the tuning dial visible behind a clear plastic chevron.

This Hi-Delity 6T-330 was distributed in America by Petely Sales Corporation, 800 Park Avenue, South New York.

It is very small measuring just 90mm x 60mm.

This Hi-Delity comes with a luxurious hinged wooden gift box! It also comes with a leather case, leather earphone case, earphone and instructions!
