power lead for a HP procurve 1410-16g switch
anyone have any idea where i might source one?
I've looked thru a truck load of leads we have at work, and i'm damned if i can find the appropriate one.
The connector is meant to convert to 12v 1.08amp, and any i find that are 12/1 have slightly larger ring so won't plug into place.
Utterly devoid of ideas on where to source the appropriate lead, as anything on ebay seems generic, and i feel won't fit like the 3 or 4 generics I've found.

Ive bought a few universal ac/dc adapters from amazon before, they come with several tips and sizes are shown on the site, will cover up to 2a also.

I've got one of those switches and the HP part number printed on the PSU is 5066-1112 (12V 1.25A) (Model EADP-15DC A).

There's a secondhand one on eBay for £20 at the moment.
