Cosmetically this unit is really in excellent condition. It is very nice with a good roll chart. Functionally it calibrates line voltage fine, but when I tested a tube the meter pegs (see last photo). This is all original, so I suspect if you\'ll clean all the switches and pots and replace the very few old capacitors it will work like new - certainly the transformer is good and that\'s the only irreplaceable part in the whole unit.
