Of course, Kenwood is known for their quality tuners and the KR-4070’s tuning is no exception. The Loudness control is also very good and contours the sound perfectly for low level listening.

If you run across a KR-4070 you will probably find that some or all of the dial lamps have gone out. These are fairly easy to replace and are basic 8V 300mA fuse type bulbs and can readily be found on eBay.

Kenwood KR-4070 Inside

Another issue that is common to Kenwood receivers of this era is the power switch. Despite the good build quality of the Kenwood line the power switch was, for some reason, an exception. It tends to fail over time and many Kenwoods you’ll find today have an issue with it. There are a few fixes that can be found online that include cleaning the switch and replacing the wiper or installing a relay. The KR-4070 measures 5 7/8″ x 18 1/2″ x 11 13/16″ and weighs just under 21 pounds

Despite its minor issues the Kenwood KR-4070 is a great receiver. As mentioned previously it is a no frills stereo but it is built well and performs fantastically. You can find them for about $80 to $200 depending upon condition which is a bargain relative to other similarly rated receivers.

Kenwood KR-9400

The Kenwood Kr-9400 is one of Kenwood’s iconic receivers from the mid 1970’s and was their top of the line receiver at the time. At 120 watts per channel into 8 ohms it was an early predecessor of the later monster receivers. It debuted around 1976 and retailed for about $750.00.

The KR-9400 features the classic Kenwood styling from the 1970’s. Blue, green and red lighting on the dial and meters makes for a colorful display. The volume and tone functions have detent controls. Kenwood uses a triple function meter for Signal Strength, Multipath, and Deviation depending upon which button is depressed. It also features triple tone controls and a Dolby FM switch (requires a Dolby adapter).

The build quality of the KR-9400 is exceptional. The pre-amp utilizes low-noise, metal encapsulated transistors to give it a high signal to noise ratio. The FM decoder has phase lock loop IC circuits which allow for extremely high FM stereo separation. It also has a large power transformer and huge heat sinks.

There is no coupling capacitor between the output and speakers so total harmonic distortion is very low at 0.02%. The KR-9400 is easy to work and is laid out very nicely. It also has real transistors as opposed to the hard to find power packs the KR-9600 has.

When Pioneer came out with the SX-1010 at 100 watts per channel, Kenwood responded with the KR-9400 at 120wpc. Marantz then released the 2325 at 125 wpc. The watt wars then began in earnest through the late 70’s and into the early 1980’s.

The Kenwood KR-9400 didn’t sell as well as the Pioneer, Marantz, or Sansui top of the line receivers though. Maybe that’s why they are harder to find these days. The KR-9400 performs well though, is exceptionally built and is reasonably priced relative to it’s competitors of the time. The KR-9400 sells for about $400 to $600 depending upon condition.
