You are looking at a vintage Wards sound equipment piece. I think it is a guitar amp but not positive. The tubes light up when I plugged it in. Other than that I have no way to test. The unit is very heavy at just under 50 pounds. It is 18″ wide X 10″ tall X 11 deep. I have pictures that should show details and condition.
