Profoto 1a for Nikon. Purchased on Yahoo Auctions for 76,800 yen, it stopped firing after being used twice on location. It has been stored in my equipment room at home for 2 years since then. It has not been dropped or bumped. The continuous light function works. When I press the test fire button, it beeps, but it doesn't flash. I took photos of the flash tube section after removing the screws, so please refer to them. The exterior shows some signs of use, but it's not too beat up. I would appreciate it if anyone who can repair it or wants it as junk would consider purchasing it.
