AP-8 Power consumption?

[davidf]

Does anyone know what is the power consumption (e.g. mA at 12v) of an AP-8 when:
-- in 'lo-volume' mode and not playing anything
-- in 'lo-volume' mode and playing
-- in 'hi-volume' mode and not playing anything
-- in 'hi-volume' mode and playing
I realize that consumption when playing will vary depending on what is being played and the on-board volume control setting, but any measurements would be welcome.
Thanks in adavnce,
David
