Onkyo FM/AM tuner built-in amplifier R-810M (made in Japan, of course). Operation confirmed. Sound was produced by connecting a portable player to the CD terminal. Other terminals have not been tested. FM reception was successful, but AM reception was not. The item for sale is the main unit only; there is no remote control, instruction manual, or tuner antenna. Detailed operational checks have not been performed. The exterior has small scratches and dirt that are noticeable upon close inspection, but I believe there is no major damage. Please understand that this is a no-claims, no-returns sale.
