Heathkit Color Bar & Dot Generator. Model IG-5228 - Powers On W/ Manual. I got this from a tv repair man. I bought 4 heath kit pieces  and sold two. All customers are happy as the man took excellent care of his equipment.  I dont know how to test this generator, but it powers on. Im sure it works based on the mans reputation.  Good overall condition for its age with normal wear.  Please see all the photos.
