Cool estate sale find! When I say it works, I mean I plugged it in and could hear static through the speakers. I don't have a mic or knowledge of how to test further than that. 

Please see pics for cosmetic flaws. Handle is missing but the rest appears to be in pretty good shape.

Measures 17.5" x 10" x 8" and weighs 20 pounds. Several shipping options are included and local pickup is available in the Dallas, TX, area.
