anyone in UK using US plug mains?

[no32]

I've often thought about using the old 15A round pin plugs. These have an earth prong and no fuse. The plugs and sockets are easy to come by, new on eBay. I've got a double gang socket and two plugs floating around in the shed, so I could power both of my amps from them. The dedicated spur feeding the existing sockets has its own fuse, so it should be safe to use, I guess. I might get round to trying them one day!
Has anybody used these?

Are you referring to these ?
They are very good

Im my mains cables who fitted with plugs I use copper or silver plate that push the cable and than i solder it or use locktight to prevent the screw to open.
