I bought this used Cambridge Soundworks 15volt DC adapter for a Bellari VP130 phono preamp which uses 12-15 volts (though one advertisement says 18volts also). This says it is 15 volts but a volt meter says it is over 18. None the less I have tried it on the Bellari it plugs in perfectly and seems to be working great so far.
This is a functional, exact replacement for a Cambridge Soundworks DTT-25000 system. It works as expected. Even though it is out of sight, the power supply is in pristine condition.
