I haven't been following this thread too closely, but what I have seen is simply confusing, so I thought I'd throw in my twopenneth worth.
Firstly, many of the components which make up devices like a PowerCD, i.e. transistors and diodes (and chips, which are made up of thousands of miniature versions of these) simply don't work with AC power, for reasons which I'm not going to go into here. So, almost without exception, all these devices require a power supply which can turn the AC from your socket into DC which the device can use. It almost invariably DOES matter about the polarity of the power supply. I've fried various devices over the years by taking a fifty-fifty shot on this and getting it wrong. Some devices have protection against this, but others don't. Your call. If the polarity isn't marked on the PowerCD you could dismantle it and try to trace the wires from the battery bay to the point that they join with those from the external power adapter socket to work it out. So, to summarise - the PowerCD almost undoubtedly ultimately runs on DC, either from the internal battery bay or from an external power supply. HTH Mike > One other question comes to mind now.
