Default Radio is killing my battery!

My 94 ES 300 recently failed to start - I found the battery had gone dead. After some basic troubleshooting, I found that the radio circuit was causing a .7 amp drain on the system. Where is the relay that drives the radio circuit? Disconnecting the power amp or antenna did not cure the power drain. My wife will never allow me to simply pull the radio fuse!
