[QUOTE="PaulR, post: 87605, member: 176256"] Going back a few decades It was inadvisable to switch on a valve amplifier without a loudpeaker to load the ouput stage. Without the load there was a large back emf which could spark across the valves and/or transformers. When transistors arrived the position was reversed. Short circuits were the new enemy whilst leaving the output unconnected had no effect. What's this got to do with satellite receivers? Probably nothing. PaulR [/QUOTE]
