Re: Which power supply for Grundig Yacht boy 300?
The schematic, which is available on this site, tells me that the centre pin is positive and requires 7.5 volts. I see that a Sangean DAB Radio 7.5 volt power supply, which has the right polarity plug, costs £9 from a well known source. What I can't tell is if the plug diameter is correct. A little work at your end will solve the question.
