Its a for a Bush radio .The original broke so I bought this one online from a third party and it descruibed the itej as matching the radio in question .The requirment is 6V DAC 1000milla. whilst the adaptor (which is part of a plug attached to a mains lead) states 6V Dac 2000milla.I subsequently read that hte radio will extract hte amperage it requires form the adaptor. What concerned me though is that when i first pluged in it crackled .Now it seems fine but I am still apprehensive .I have a modern consummer unit so presumably the trip switch would go off if anything went wrong.Should I be concerned ?
