- =======================================
-
- If you generate a stabilized voltage with a linear-mode- or switched-
- mode-power-supply you are never shure if the circuit goes damaged in
- worst case. About this you must think, because a CD-Player is an
- expensive device. You shold save your CD-Player with an additional
- power-zener of about 3.6V and a fast-fuse in serie of it.
