12v trigger - could I use it to power a phono preamp?

    I just got a receiver for my office to replace the one there - massive change going on that system is getting a big overhaul. The new receiver does not have a phono preamp built in so I was planning on purchasing something like a Rolls VP29. Question: Could I use the 12v trigger output as a power cable to the Rolls? Sure would be slick if I could do that instead of running a wall-wart. I've used a wall-wart connected to the switched power outlet on the back of a receiver before, so I figure why wouldn't this work?

    12 volt trigger won't work to power a phono preamp, only to turn it on or off. You would still need to plug the preamp into an outlet

    Trigger means it sends power only when the trigger executes, not otherwise. It's just a brief output of power.
