I've had a few of these....I always end up giving them away for some reason. What a great little unit. I would love to have a single product or two like Ameco that is the go-to product for some niche function. Ameco was a first class act, going back to the Nuvistor converters. I also have the Ameco 78 rpm code practice records. Anyway....nice to see Ameco stuff come up on Zedswap from time to time.
