Effect of two power prongs, not three

Almost every power cord I have seen has a three prong IEC female connector socket ("C13"). My amp (Myryad) has only a two prong male IEC ("C18"). Wikipedia states that the C18 does not have a third pin for earthing and also states that a "C18 inlet will accept a C13 line socket . . . .� Any problem with buying a standard cord with a C13 socket? Any problem with lack of a ground?

A follow-up to my previous post. I took a look at what was probably the same Wikipedia writeup that you referred to. If your amp inlet looks like this, then you should be ok:

My concern had been that there would not be sufficient clearance around the inlet to insert the part of the cord socket that has the third pin.

Yes, there is no problem electrically. But I'm not sure that a replacement cord with a 3-prong female socket will mechanically mate with your amplifier. The statement about a C18 inlet accepting a C13 line socket I believe refers to the fact that a 3-prong wall outlet will accept a 2-prong plug.

No problem. If your amp only has a two prong male connection, then it will be double-insulated and will not use the chassis as the common ground; it's been designed that way, so probably best not to start trying to earth it yourself.
