Are you sure no components use AC? Since (depending on what the device
draws) the actual resulting voltage could be anywhere up to 12.7 V, I may
need an adjustable (or higher-voltage) xformer. Also, depending on
transformer sag, it could be below 9 V. A 9 VDC transformer would probably
have about the same voltage characteristics if everything works right.
