Has anyone replaced the power chord on their Marantz Denon Pioneer yamaha etc AVR? My Marantz only has a 2 pin female.
Many mass market audio devices have only "live/hot" and "neutral". The third connection "ground" pin is not provided.
If your concern is "will 3-pin after market cables work on a 2-pin system?" then read on. Else ignore.
In after market cables, and if they are 3 pin, the direct ground connection is not active. It will still fit the 2 pin male on the equipment side.
Is this a problem? Not really.
Neutral is grounded or earthed at the distribution box. It provides a return path for current flowing through live/hot wire.
The provision for ground pin/connection is desirable when the equipment is connected directly to the wall to prevent electrical shock.
The ground connection is desired because it provides a "short" path (pun intended) to earth/ground rather than via neutral at distribution box.
In the event of a fault, and you touch the equipment, you don't become the "short" path, if the ground connection is wired.
As I have said earlier, if one uses a spike guard or extension box, these are usually 3-pin active, thus preventing accidents to due electrical fault.
Edit: Yes I have tried my power amp (3 connector cable) on IA and AVR (both Marantz devices). No issues.
