Polarity on a non-bladed plug?

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.

Jea48, if you actually measured the 'potential' at neutral or ground, you would find that it it varies from positive to negative at 60 Hz frequency, thus making it symmetrical! Capacitance (and inductance, for that matter)only exists in AC circuits where polarity essentially changes 60 times a second. Can't be more symmetrical than that. Hum, however, can exist due to different potential at the ground or neutral at different places. That is why reversing 'polarity' might make a difference.

Understood, Jea48. I understand the difference in the use of the term 'polarity' for AC circuits versus DC circuits. This difference, unfortunately, is not understood by many, however. The incorrect use of the term 'polarity' to describe ensuring that the grounds/neutral are all connected and that the 'hot' side doesn't appear at the nominal chassis ground, always leads to confusion.

The reason that I wish to remind people that AC has no polarity is to rid them of the fallacy that there is only one direction for the current. This is not true, therefore all 'mumbo-jumbo' about assymetrical AC circuits and where the hot and ground leads (which are incorrectly referred to as positive and negative) are located making a difference in sound, such as the contention with the transformer leads, is just that, 'mumbo-jumbo'. Any difference to the sound due to reversing the plug is due to a change in the noise or hum which might appear at the audio line chassis connection, not transformer configuration of hot and ground connections being asymetrical, etc.

These guys would also disagree with you.

Then we shall have to remain in disagreement, since I can, of course, list a bunch of people who would agree with me and we would just have a 'pissing' match!
