Vintage 90's Sony Dream Machine Alarm Clock Radio 📻

Used condition, but no overt physical flaws. Needs a detailed cleaning. I tested the following plugged in: -clock -- ok -alarm -- ok, but both buzzer and radio go off. There's the option to choose either but I don't think it works -radio -- ok -volume -- can get low but not fully off -radio tuning -- ok -snooze button -- ok -sleep and alarm reset not tested -not sure if it runs off batteries. The one in there has probably been in there for awhile About 4.5" cube
