Viz Isotap, Yes, I am familiar with this unit. I use to have one and I gave it to a friend,when I upgraded. It was made for RCA. It is an Isolation Transformer. It had about 6 or 8 sockets on top to select different AC outputs. It's main use was to Isolate the chassis you were working on from the AC Line. Its main drawback was that it didn't have enough variable outputs, and it only had 2 prong sockets in the output, but it is still a good unit, with limited use. Viz made several pieces of test equipment and I think it was owned by RCA.
