Re: buzzing power supply with 2nd hand M15

2008-11-12 by elemental

Ok. I think I've worked out what happened. The guy who sold it to me
sent it with ribbon cable attached. I assumed that the power end would
be the right way round. Well, I compared it to some other cables I had
lying around. Looks like it goes the other way... anyway, I've tried
with some other cables (I assume all the right way round now) and all
I get is some DC click when I connect any of the outputs. I think I
burnt it :-(

If I have, is there any way to repair it?

Thx
