Russ Andrews Claim.......

The figure of eight mains leads are only allowed to be used on equipment that is double insulated & with no earth.

So effectively it doesn't matter whether the Live or Neutral in the mains lead sees the internal fuse, because you can't short a damn thing to earth as there isn't one

It won't make a crap of difference which way the connector is connected

[DSJR]

I'm afraid it does Mark Done it with so many Philips based CD players and could hear it blind... Philips leads had a little tongue on the back end of the plug to aid "polarity."

Easy really, from my numpty perspective anyway. The "best" way round for a fig-8 mains cable was to keep the brown live conductor connected to the pole of the unit with the inline fuse.

Ah well. I happily admit to being a numpty, but I heard what I thought I heard

[Reid Malenfant]

Polarised plug? New one on me Dave, but if so then maybe the machine was using the Neutral (which is at Earth potential as they are wired together) to sink some noise via capacitors (filtering).

No idea, but the polarised plug is also a new one, so...

Absolute Foo, IMHO as always...

[DSJR]

Sorry, I mean the low current fig 8 mains plugs as used on smaller gear. Are talking about the same thing here? Polarised as in one pole is hot and the other neutral, not "polarised" in the peter Belt sense.......

Yes I think so Dave, but they can be inserted into the socket either way from all that I have seen

Never seen one that you can only insert the plug one way round, though yes, one of the terminals is Live & the other is Neutral.

Now are we on the same lines

[synsei]

Some Philips products are supplied with what is best described as a 'B' shaped plug rather than a figure of eight. I think it is this type that Dave is alluding to Mark.

[DSJR]

No, what I am referring to is the Philips reverible fig-8 mains plug. Put it in either way round () but I seemed to find, back in the good old days when I cared about such things, that the sound was slightly smoother on a CD player if the plug was aligned "correctly." Now, since CD players back then sprayed all sorts of muck down their signal lead screens as well as back into the mains, I'm sure that any difference could be measured. Cripes, if I can hear it, it MUST be measurable

[Reid Malenfant]

Yes, that's what I thought Dave might be refering to, Dave

But I have never seen one myself, might have seen a picture of one though


Sorry

Ah, gotcha Dave, took my time

I thought about this earlier & while I'll not say I agree with you, because I can't see how it could make a difference, you have me wondering

It's something I have never tried, as I have just plugged them in & not swapped them over.




You just might have done me a favour


Why didn't I ever even consider it? Because in theory it shouldn't make any difference if it's double insulated
