Gambro model G10 rectifier

Hi - I found an old Gambro electro-plating rectifier, Model G10
hiding in my studio for 12 years. Came with an estate lot, and I put
it away, forgot it and recently found it. It does work. However, I
can’t seem tofind a way to use the cables, for they have a metal
prong that fits into the machine, and into an electroplating pen,
which I don’t have. I would like to use it for goldplating and
rhodium-plating, so I would need something with alligator clips. Ebay
has lots of those models around but not so much in cables/leads.
Would appreciate any help on this. Thanks Joy
