Power connector cable 2.3mm ID?

[Ancient Mariner]

Can anyone recommend where I can get a power connector cable with an internal hole dia of 2.3mm? All the standard ones are 2.1mm, and won't fit my Rocktron chorus pedal.

Thanks

Never come across 2.3mm. 2.5mm is the next size up which are readily available.

Maybe it's 2.5 then - thanks.

Must look a bit harder if they're readily available - I bought a correct sized plug from maplin, but it literally fell apart in a couple of weeks. Also tried drilling out an existing plug, but that wasn't helpful either.
