I think we all know that the switches on our Drakes are difficult if not impossible to source. They have only so many mechanical and electrical cycles before they fail.
So what are the advantages of inrush NTC resistors, step starts, offload relays, or ??? I've tried to think through the theory, but honestly I am not sure I can rationalize a single good solution. It looks to me that there are two electrical events that stress the switch. Turn on with high current, and turn off with "self extinguishing" AC arc (except for the TR7 which also has DC switching, but low voltage so small arc). So what option is best and why for electrical stress? So far my solution on 120 VAC has been a computer power strip with individual switch per AC socket. I think that saves mechanical and the worst of the electrical stress.
