Akai AT-2450 (1979–1980)

A Japanese-built FM/AM stereo tuner from the turn of the 1980s, noted for strong FM performance and serviceable modern usability with basic restoration.

Overview

The Akai AT-2450 is an FM/AM stereo tuner built by Akai in Japan from 1979 to 1980. It was sold simply as a tuner, and it belonged to a small series that included the AT-2650. Documentation is sparse. Surviving units show it was built to be serviced, and some technicians have reported replacing most of the internal capacitors during restoration. The front panel is silver and black. It was made during Akai's late 1970s push into high-fidelity audio components. One technician called it a "rather impressive tuner" after servicing it. An owner has noted it outperforms many modern tuners in sound quality, and compares it favorably to the Magnum Dynalab MD-90T.
