Description

Hello thank you for viewing my listing!
So what i have here is a beautiful enlarger in excellent condition, however when i purchased it the power cord was cut, so i purchased another power cord but upon installing the new cord i cant remember how to reinstall and i dont want to install the cord end into the wrong side and blow the machine up or damage it in any way. As seen in pictures you will see where i took pictures of what i dont understand because im not a electrition by any means necessary, you will see the 2 bigger prongs are to the power cord the other 2 smaller prongs plug in beside where the power cord plugs in and get screwed in but once again i cant remember which go where.
So basically i was told it had been sitting for a few years before i purchased it and it worked flawlessly before it was put away in the garage.
It is listed as parts or repair only because i dont know how to reinstall the power cord and other 2 cords not plugged in and i haven't tested it.
All parts should be there as seen in pictures.
If you have any questions please ask and i will try to asnswer as best as i can. Thank you!
