Does anybody know the amperage rating on the Becker radio fuse? There is a small fuse in a plastic holder in the back of the radio. The fuse on mine burned out and all I can see on the fuse is 12/250V, which makes little sense. Obviously 12 Volts, but should be maybe 1 amp fuse? What is the maning of the 250? Maybe 250 miliamperes, which is 1/4 of an ampere? It is a traditional tubular glass fuse with a thin wire in it and it was full of white powder.
