Trio WX-400 valve (tube) receiver
(tuner amplifier.) 1962
Little is known about this very interesting unit.
It is likely to have been built between 1960 and 1962.
Kasuga Radio Co., Ltd was established in 1946 and renamed Kasuga Radio Industry Corporation in 1950
and then again renamed in 1960 - Trio Electronics, Inc.
In 1962 Trio introduces the first transistor products and by 1966 all products are fully transistorised.
This Trio WX-400 receiver was also known as the Kenwood KW-70.
Trio eventually became known as Kenwood Corporation. (Kenwood Electronics in the UK).
In the States Trio has always been known as Kenwood and it is likely that the Kenwood KW70 was the
US version of the Trio WX-400. There was also a WX-500 although not sure what the differences were.
The WX-400 has 22 valves and is an AM/FM Wide Band Stereo Receiver
The appearance, with it's chrome edging is typical of early Japanese domestic Hi Fi and consumer electronics.
It has been in the collection since the early 1980s and was bought from a friend. There is almost
no information about this unit on the internet and as usual manufacturers web site are of no help.
Any information would be most welcome.
