There is not a lot of information on this classic Kenwood KW-70 tube receiver from the early 1960’s. It was also badged as a Trio WX-400 in Japan. As you know, Trio later came to be known as Kenwood. It was also possibly the higher end unit of the line since there was also a KW-44 and a KW-60.
The Kenwood KW-70 has a “Tuning Eye” which was somewhat popular in the older receivers of the time. Basically a horizontally mounted tube glows brighter as the signal strength gets stronger. The unit also featured stereo FM, separate bass and treble controls and a headphone output on the front panel.
The KW-70 uses fairly common tubes in the output section which is a plus as well. Given that the KW-60 has a power output of 30 watts per channel it can be assumed that the KW-70 puts out about 35 watts per channel.
As you can see the under side of this receiver is a rats nest of wiring. This unit has also had all the gray colored coupling capacitors changed out which is pretty much a necessity in this receiver.
Tube receivers are always popular with both collectors and audio enthusiasts. This receiver would also be in demand from mid-century collectors and decorators as well. Because of this prices are relatively high.
