Hohner Clavinet string replacement

[Aart in America Piano Services]

Hello List.

I received a call today from a customer who has two broken strings on a 
Hohner Calvinet D-6.
Can someone please advise what type of wire or strings are needed to 
replace C5 and A#5.
If my memory serves me correctly they look similar to guitar strings.
Any advise would be greatly appreciated.

Thanks,

Aart Markenstein
