This wonderful Constant 6T-200 was manufactured in Japan by Constant circa 1959. Constant was a brand name used by Fuji High Frequency Radio Lab, Co Ltd who in turn may have been a subsidiary of Fuji Electric Company 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, Hi-Fi and probably others.

Other than that I know very little about Constant.




This Constant 6T-200 features a stunning reverse-painted face reminiscent of the speedometer found on a classic sports car! And the tuning dial is reverse-painted as well! 

It measures just 112mm W x 70mm H.





This Constant can also be found branded as a Jupiter. It uses the same cabinet as the Vulcan 6T-220 pictured.





This Constant uses 6 Toshiba transistors.
