Hi.
i'm looking for a small pre-amp. Simply to put between a portable cd player, and a pair of these small portable speakers (the sort that are driven by the headphone output on the cd player, and consequently arn't very loud).
It has to be battey operated, and I would prefer not to use op-amps, because presumably getting the negative voltage would waste some power. So a transistor based one would be good, but because of the battery operated nature, I don't want anything that will draw too much power. It only has to drive a pair of speakers with a similar impedence to standard headphones.
Can anyone provide a diagram/suggestions?
Cheers,
Tim
