Made a monthly visit to Goodwill this week to drop some donations off. Had a look inside the store at the electronics section. I spotted a nice shiny Grundig S350 for 20 bucks with the power adapter. Inside were 4 D batteries. The adapter had a crack in the case and it looked like someone tried to glue it. It would not power up by battery or cord. So I bought it and left the adapter behind. When I got home I tested the batteries and they were dead. I had no D cells at home. I have no desire to power it with D cells. I found a 6V 300mA DC adapter in the junk drawer. I had to cut the cord and reverse the polarity to match the specs of the radio. Plugged it in. No power. Big disappointment - first shortwave radio I ever found at a Goodwill. I know there are a lot of these radios around and they have a bad reputation. Outside of buying a pack of D batteries does anyone have an idea of anything else I could try? If it doesn't work I do have the option to return it. I really don't own any test equipment. Is it worth the hassle or should I junk it?
