I was given a dusty old KW transformer from a neighbor. Needs some new knobs. The
cord is really frayed and needs replaced. I also can feel movement inside if I turn it
side to side. I plugged it into a power strip and stayed back when I turned it on. It makes
a humming noise, but no smoke or bad smell. What is involved in replacing the cord and
making sure it's working OK? Is this something I can do? If not, is it worth spending money
to repair since there is probably much labor involved? Thanks in advance.
