Kenwood KA-1400B – vintage stereo integrated amplifier – around 1975 – fully tested
Offered is a fine Kenwood KA-1400B Solid State Stereo Integrated Amplifier, a classic Japanese amplifier from the mid-70s.
This unit is in very good cosmetic condition considering its age of about 50 years. The wooden cabinet and the dark front give this amplifier the typical and attractive look of Kenwood equipment from this period. See the photos for a good impression of the condition.
The amplifier has been fully tested by me and found to work well. The various inputs, controls and speaker outputs have been checked.
The KA-1400B features, among others:
- two phono inputs
- tuner and AUX input
- connections for two tape decks
- connection for two pairs of speakers (A and B)
- bass and treble control
- balance
- loudness
- high filter
- mono/stereo selector
- headphone jack
- microphone input
- switchable mains voltage 120/220 V – 50/60 Hz
- Made in Japan
Because this amplifier still uses the original screw terminals for the speakers, a speaker adapter I made is included. This allows speaker cables to be easily connected via the convenient spring terminals, without modifying the original amplifier.
Also included is a US-to-EU adapter plug.
