Thanks Phil, Eric, maxhifi, I found a EICO 667 on ebay 50 dollars with three days left. Just looking at it it doesn't look like it has very many different socket bases. Nothing on the Accurate Insterments model 257, found several Mighty Mites and a very pricy TV-7. The Mighty Mite is probably what I'm looking for. There are several different versions for sale on ebay right now and looks like manuals are available too. This one looks like a good one to go after..
