I was using these until a few years ago, but I'm selling them now to organize my equipment. Each piece of equipment has been tested for power and operation. I confirmed the enhancer's operation, but only the presence lamp doesn't light up. There are no paper manuals, but I can provide them on a data medium if you wish.
