Over-powering a linear power supply causes rectifiers, ballast resistors and regulation circuit power transistors to run hotter than they were intended to.
Depending on regulatory requirements in electrical codes, they may have specific requirements for switching the hot -and- neutral wires, fusing and depending on mains voltage and sometimes frequency differences in some parts of the world, the primary windings and magnetic circuit in the core of the power transformer will be rated for different voltages and frequencies. Most audio gear is made with different transformers for different markets. You would need to check the labels to be certain.Īs Al wisely pointed out, the power supply in the CD player is likely a linear power supply, and designed to operate within specific tolerances for the target market. Geoff: Modern switch-mode power supplies are often auto-ranging as far as input voltage is concerned. The higher the pressure (voltage) coming in, the faster the dam fills, the easier that is.

We want the dam full at all times, to help keep constant water pressure coming out the other end of the hose.

Which they do, just never as good as we'd like, which is why power supply mods and things like dedicated lines, power cords and conditioners matter so much.īut remember I said it was not just wrong but backwards? I'm gonna use the usual water metaphors here. The idea is the caps, in storing the power also filter the noise. Whatever the incoming voltage, hardly matters, because it is gonna be stored in caps anyway. The challenge with regards to incoming voltage isn't the voltage per se, but the noise riding on the AC line. The challenge in building a really good regulated power supply is in maintaining constant voltage in the face of wildly varying swings in demand. This is so far beyond wrong its backwards! The voltage regulators in the DC power supply are working their butts off trying to maintain a constant designed rated voltage.
Yes it works, but the life of the CDP will be shortened.
