add remote control AC on/off for power amp?

I am moving from tube to solid state amp and want to be able to remotely turn on and off the amp with the rest of my system. I assume there are remote AC on/off devices out there? Which are suited for a 100 or 200 watt/channel amp and will not limit current?

My preamp may have a switched outlet but I thought that would not be best for them to share a power cord.

thanks for any thoughts.
