Kenwood KW-70

Kenwood KW-70

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. A fully functional KW-70 can sell for over $500.00 with average units selling for about $300.00.

  1. Reviewing the factory owner’s manual for the KW-60 model posted on revealed the power rating for the KW-60 was 30W per channel. The owner’s manual for the KW-70 is not posted, so you have to use logic to assume if Kenwood named the KW-60 for its 30W/ch rating, then the KW-70 should have 35W/ch, not the 10W or 14W you assume in the description above.

    1. Yes, I think you are right. I just checked hifiengine’s manual for the KW-60 as well and it does state 30 watts per channel. I will make the change to the post. Thanks!
