Hello all,

I received my K40 and I seem to be missing a connection on the power supply. It seems to be missing the K- connection. I am wondering if anyone has a similar power supply that could tell me where this is supposed to be connected so I can fire this puppy up.

Thanks!

Well this is a very old thread so hopefully the poster solved his problem already but if you have one of these all in one supplies I know a little about them. The K- lead is not connected to anything because the button board has another ground connection so the k- isn't needed or used. The k+ gets grounded by the "test" switch to fire the tube during testing.
