Up for sale is a working Superior Instrument Co vacuum tube volt meter, model 77 with a blue plastic case and a good, flexible, nice set of probes. As can be seen in the pictures, a battery did leak inside the item, but not bad, causing no serious damage. The meter powers up and the needle moves, depending on what position the switches are clicked to...however, it needs a recapping and calibration to be accurate and dependable.
