Durst cold light power source
Whilst rummaging through a disused darkroom I came across a Durst Laborator cold light head. Unfortunately the power source was not with it. I have two questions:
1, how can I check it to see if it still functional before I invest any time or money on it?
2, assuming it is ok where can I obtain a suitable power pack at a reasonable price?
I live in the back of beyond so all dealing would have to be by post.
I've attached a photo for identification.
Thanks in advance for any suggestions.
