The Sony MR-9100W Matrix Sound System is a vintage FM AM radio perfect for collectors or enthusiasts of vintage audio equipment. Item has been tested and is in working condition. Few cosmetic imperfections on the unit.
Unit is tested with AC Power and is working but has some quirks. The FM St switch plays music very quietly compared to the normal FM or AM switch. Also the volume fluctuates at times. I’m not sure if it is due to a weak radio station signal or not. Has not been tested with batteries however the terminals appear to be clean of much corrosion. It’s a nice clean unit overall.
