In Reply to: Musical Fidelity X-Act (DAC) power adaptor posted by MikeAnd on May 13, 2005 at 10:45:04:
Voltage and current delivery are fine. The only other issue is making sure the right part of the connector is hot.What's that smell?

Hi. Actually, it's 12 Volts Alternating Current (VAC). There is no + and - like in DC. (So it doesn't matter.) Note that 12 VAC adapters are a lot less common than 12 Volt Direct Current (VDC) ones, which definitely do have a positive and negative. Please make sure that Yamaha adapter is AC and not 12VDC. (It might actually work, depending on the circuit inside the X-Act, but I wouldn't do it.) Anyway the fact that it can deliver more current is better, but of course the voltage must be right. Just check that it's AC.
I missed the fact that it was an A/C adaptor.
The adapter is definitely AC. I'll give it a shot. Thanks!!!
Can you explain the part about the right part of the connector being hot? Sorry for the ignorance.
It's tough being "electronically-challenged", and into audio and guitars.
Thanks again.

Look at the label on your wall wart. It probably has a diagram labeled "polarity", which indicates which part of the connector (inside or outside) is plus, and which is minus. That's the easy part.The hard part is figuring out what your device requires. Other than to say that hopefully the connector won't fit if it isn't right (and I'm not sure of that) I can't help you there. That's the risky part.
Is there anyone else who can help this person? How can you tell which is plus and which is minus, without having the original converter handy?
Jim,
There's only one cable/connector coming out of the wall wart, and it fits the only (power) input on the DAC. I'll just wait a little for some more info from others. Otherwise, I'll go ahead try it. My main question was the difference between 500mA vs. 1000mA, and if that could be a problem. You covered that part...
