I got creative with one of my first remote add ons....I took a remote control fisher entertainment center amp found a low volt winding on it's power transformer that went on and off with the remote, ran a cable from that winding to a full-wave rectifier diode bridge, and connected the bridge to a relay who's contacts are wired in parallel with my 1971 Zenith's power switch. Over two years of regular use later and it still does exactly what I built it to do.
