賣家描述
AKAI Stereo Integrated Amplifier AM-U02 – Made in Japan – Early 1980s
A fine Japanese stereo integrated amplifier from the early 1980s, combining a distinctive design with comprehensive controls, versatile connectivity and a sophisticated LED output-level display.
- Model: AKAI AM-U02
- Made in Japan, circa 1980–1982
- Designed for simultaneous operation of two pairs of speakers (A and B), with a combined impedance of 8–16 ohms
- 220V standard power input
- Separate power-supply rails and carefully designed circuitry for low noise and excellent stereo channel separation
- Distinctive LED Peak Hold display, providing a clear visual indication of the output level of the two channels
- Characteristic horizontal slider-type master volume control, centrally positioned on the front panel
- Separate rotary controls for precise adjustment of Bass, Treble and Balance
- Dedicated Subsonic and High Filter switches for controlling unwanted low- and high-frequency components
- Direct input selection for Phono (turntable), Tuner and AUX
- Headphone output
- Comprehensive recording connections for Tape 1 and Tape 2
- Pre Out / Main In connections with the original jumper links
The AM-U02 offers an interesting combination of classic Japanese audio engineering, distinctive front-panel design and practical connectivity, making it an attractive amplifier for both vintage hi-fi enthusiasts and collectors of Japanese audio equipment.
Performance and possible servicing
For long-term reliability and optimum performance, vintage amplifiers of this age can benefit from servicing such as replacing aged electrolytic capacitors in the power-supply and audio circuits (recapping), cleaning the slider-type volume potentiometer and switches with suitable contact cleaner to eliminate unwanted static crackling, and using high-purity oxygen-free copper (OFC) speaker cables.
The amplifier itself is in excellent working condition and performs properly. The cabinet has only minor cosmetic scratches consistent with its age.
Included: power cable and one pair of left/right RCA audio cables.
