Recently acquired a Focomat 1c from someone who didn't have space for it. It came to me for free by the glory of the printing spirits, I suppose. Trouble is, the power cord on the thing is something I've never seen before.
Its got three angled prongs. What sort of hoops do I have to jump through to power this? And there's another power cord, too. Coming from the base of it. Its a normal US plug, though. The enlarger is residing at a different location so I can't do any proper investigating at the moment.
The cord and the plug in the picture will run from the top of the lamp head into the top of the column. The cord coming from the base will plug into a timer. You have nothing to worry about.
Yes, this is the plug that came with the early version of the 1C, that had the round enlarger head (without the filter tray). Obviously the socket in the column receives this plug.
