The inside shows some paper capacitors (Hunts) that could use replacement. I also replaced the metal recifier that supplies the DC for resistor measurement, and smoothed its output with a 220R resistor and 470uF cap. The bridge now works fine. Some of the controls are a bit scratchy, but the potmeters are all of special quality and are probably near impossible to find in good condition.
