Does anyone have a description of the coaxial DC power connector used on various Sony products such as the VAIO laptops (PCG-954A is one of them) in order to find a source? These are the type that often have a yellow insulator in the plug and a center pin about 1mm in dia., however the O.D. is larger than the common varieties used on much Canon gear. Perhaps this is Sony proprietary but I am hoping there is a standard that permits second souring.
Thanks,
Michael
