A new development. I sent the flash back to the Nikon service centre
and they have just reported to me that the flash tube is broken -
shattered. Presumably this happened when the flash was being shipped
back to me although there was no evidence of rough handling on the
box. I would not have thought that they were that fragile.

you didn't test the flash prior to attaching it to the camera?
