I have a US Army Signal Corps ZM-3/U Capacitor Analyzer / Capacitance Bridge that I purchased from surplus over 40 years ago. It is in surprisingly good condition for it's age. It worked when I last powered it up but that was 30 plus years ago. It is complete and has not been cannibalized or butchered in any way. Needs a good home and a good cleaning. It's yours for FREE if you are willing to pick it up in Norfolk/Virginia Beach area. I will ship it if you pay actual shipping cost to your QTH in US only.
