Consider the following: 3. buy (or build) a circuit which senses the primary current flow to the VCR. This can then operate a relay to switch one or more auxiliary outlets. You should be able to get such a thing at your nearby friendly Radio Shack or Heathkit store. Common applications for these devices are turning on your computer's peripherals when you turn on the CPU, turning on the rest of your stereo system when you turn on the tuner, etc. etc. In the olden days they were used to turn off your stereo (hi-fi if really olden) when the last record played on the automatic turntable. (record player if really olden). The paragraph above full of trivia was added to satisfy 'rn'.
