Yamaha CT-800 Natural Sound AM/FM Tuner. This unit does turn on and work. I mainly tested through the fixed output where it bypasses the output level knobs and instead controlled through my amplifier. I was able to pull both AM & FM stations. The variable output is a little off— the levels between the channels just sounded off at times. A little bit of wear throughout the unit as shown, please take a close look at photos to see condition.
