I am getting ready to start working on my Scott SLRM radio. You may remember my posting about acquiring some months ago. I have been reading up on it on the net. I have also carefully read the manual for it. This has led me to have the following question, since the manual, and what I have read on ARF postings seem to be at odds. The postings on ARF seem to insist that I should get an isolation transformer to connect the unit to power or it can cause damage to the receiver. The manual instead says, when using AC, to connect the ungrounded side of the power source to pin 1, which would mean to connect the grounded side to pin 3, of the input socket, nothing about an isolation transformer. This also implies that it assumes that one of the power leads will be grounded, as is usual, as well as the actual ground which will be connected to pin 2. My question is, do I really need the isolation transformer or not? I know it wouldn't hurt anything, but is another expense, and not a small one. From AES the one I would need costs about $61 plus shipping. Any advice, especially from any of you who are familiar with this radio, will be appreciated. Below are the schematic, as well as the pertinent sections of the manual.
