Unmolested ORIGINAL ZENITH BLACK DIAL RADIO from local family estate. I have provided pics from every angle and they can be enlarged as well. Untested because of what I found below….. Question: I just acquired an antique radio. I don’t know if it works or not. Can I plug it in and turn it on? Plug in and turn on an old, unrestored radio until it has been thoroughly checked for signs of trouble. This includes, but is not necessary limited to. Replacing the electrolytic (filter) condensers. Examining the underside of the chassis, paying close attention to the bottom of the power transformer. Look for any signs of a waxy substance leaking from the transformer. If you see it, the transformer has overheated at some time and may no longer function properly (if at all).
