High swr protection circuit
Web1. I always thought that the protection circuit measures the voltage and current on the final (s) and their temperature, rather than the reflected power, since it's the voltage, current, and heat that do the damage. Reflected power causes higher voltage, current, and heat on the … WebNo high SWR protection (circuit breaker takes care of that, a bit primitive) ... The protection circuits in the SS-750 work well, I think I have accidentally tested all of them a few times. In summary, you can buy a cheaper amp than a Henry, and that is just what you will have. There is a reason some amps are readily available and you have to ...
