SUT clarification please
I have just remembered that I bought a pair of WAD/WD stepup transformers 4 or 5 years ago. These have languished unloved in a box all this time.
Anyway, I thought now would be a good time to bring these to life. Unfortunately the instructions I received from the very helpful seller died along with my previous pc. I was wondering whether any of you bright sparks could help with 2 things please; 1) The SUTs have a hand-written reference D8749. Would this be enough to confirm the step ratio? I think it might have been 1:10. 2) With a picture included below, could some kind person confirm which wires connect to where for me? Top left - 2 green + 1 black Bottom left - single red Bottom right - 1 orange + 1 blue. Many thanks for taking the time to look at this. Kevin |
