"Ron Hardin" wrote in message ... I run everything off a SS-18 (R8B and 30 ANC4's DA100E's and DSP's). I tried a RS-7A but didn't like the heat it throws off. The switching supply avoids that. I fuse the output at the supply with an inline fuse (reflecting the wire gauge), and fuse each device separately with like 1/4 or 1/2 or 1-2 amp fuses where I distribute 12v to them all. A properly working power supply can easily burn up the light wires running to these things if you don't fuse it, where the internal resistance of wall warts had prevented it before you went to a central power supply. There's some birdies from the SS-18 but they're not bad; and I put the thing in the basement and run the 12v to the first floor, so there's some distance intervening as well. It does run enormously cooler. I was motivated to get the central 12v by the heat the R8B's supply throws off, that is now eliminated, as well as the growing number of wall warts I was accumulating as I added to my phased array. -- Ron Hardin On the internet, nobody knows you're a jerk. Hi Ron I heard switching supplies are not the best choice for radios. But I don't know enough about them to really know. So you're putting fuses on the hot wire {+}coming off the PSU to the radio??
