How does that old saying go? "When in doubt, READ THE INSTRUCTIONS !" Well, I printed out the entire manual for my Scott SLRM, and have read it through. I found that, if people actually READ the manual, there should be no controversy about whether one should use an isolation transformer with this radio. Here are the pertinent sections of the manual :

So, there you have it. If your house outlets are properly polarized, and you connect the inlet connector properly, you should not need an isolation transformer. I DO in fact have the original, proper power input connector to mate with the socket on the back of this radio, and it is clearly labelled with 1, 2, and 3 for the terminals. So, black, or hot, the narrow blade of the plug, goes to 1, the white, or neutral, the wider blade of the plug, goes to 3, and the shield, or ground, goes to 2.
