Polarity on a non-bladed plug?

I don't need to read them. If you think it sounds better one way then that's the way it should go. I bet you can't tell the difference.

Rwwear, while it might not make a difference sound wise, it might make a difference 'hum' wise. If no hum present, then I agree, since AC does not have 'polarity' as DC does.

1) Reversed AC polarity -- All power transformers have an inherent asymmetry to their construction. The primary winding comprises multiple layers, so that one lead is connected to the innermost windings and the other lead is connected to the outermost windings. This means that one lead has a higher coupling capacitance to the core of the transformer. Please remember that the AC supply is also asymmetrical, with the neutral lead essentially being at ground potential (assuming there is not a fault in the house wiring). The result is that one orientation will give a higher AC leakage current to the chassis of the amp (and worse sound) than the other orientation.

Not all transformer manufacturers use consistent markings on their transformers so that the correct orientation can be identified, and not all amp manufacturers pay attention to this even if the transformer is correctly marked. The result is that many audio products have a random chance of being correctly oriented.

What you say may be true Jea but if the plug is not polarized then it should'nt matter. If it does, turn it the other way.
