He should be able to tell you if it's AC or DC. If he can't do that then tell him to find another job. The output will be low since the input will be 120v instead of 240v. You will need an adapter/transformer which gives about 2 times the measured voltage and a minimum of 300 milliamperes (500 milliamperes would be better). The voltage needed may be less since the adaptor will have no load attached when measureing the output. As a reference I have a Fidelity Mach III Master which runs on 9v Dc/350 milliamperes. My Prestige needs 8v AC/1.5 amps. Both are much more power hungry than the CC10. So the bottom line is it will probably need 9v DC/350 milliamperes or about 8v AC @ 1amp. I suspect neither is critical since the unit probably has a 5 volt regulator inside. Good Luck
