Heathkit Model IG-1275 LIN/LOG Sweep Generator - Powers On - Read Description. I picked this up at an estate sale so I don’t know a lot about it. It powers on, but beyond that, I don’t know how to test this. The body has some splotches and some of the screws are rusty. It could use a good cleaning between the knobs. It also the face is slightly wavy in a few area.
