JMFahey, you are making an unusual mistake and I'll leave it at that as it is embarrassing. Sorry.

I have examples here like this and one of them is playing every day so I can back it up with practice/reality (otherwise I would not have given any advice). It seems you haven't experimented in this direction.

My understanding is that a given circuit will pull only what it needs and no more (operating properly of course). The power source will give only the amount asked up to its own limitations. Yes, there are losses coming and going, but these things aside, I don't see any real trouble except for the fact that at power up, this 2K transformer will be a problem for inrush current. After that I suspect that whatever idle current is being drawn as a whole is not that great.
