A few years ago I saw a Crown K1 power amp listed for sale. The owner stated
that it was not functioning, so I figured that, at the worst, I could use it
for parts for projects.

So, I bid on it and won it. When it arrived, I unpacked it and hooked it up.

It worked.

I turned it off and set it aside for a few days. When I tested it again, it did
not work. The old thump test showd that there was an intermittent connecton.

When I took off the top cover, I noticed an torroid type inductor on a circuit board
was positioned (bumped over) in such a way that it might be touching the amp's case.

I straightened it up and put some silicon sealant on the side that was nearest the
case.

The K1 has been working fine ever since. Very nice amp for suboofer use.
