Just an update on the Jackson unit. The thing is both larger and heavier than I suspected. It's built like a tank with superb craftsmanship and/or quality. The "meter" I was excited about was not a meter as another member suggested but simply a scale to reference the bridge and unlike most any Heathkit I have run into, it reads spot on no matter what I am trying to read (paper,mica, electrolytic, resistor).
To describe this unit's quality in a comparison the name that comes to mind is Hickok. Some may not agree, but I love Hickok stuff. Actually, I've never seen a cap leak tester by them, but the old 209 series meters and the same period tube testers are great!
Back to Heathkit C3s, I have found that for some reason the older, tan units often show up relatively if not exactingly precise in bridge readings and close enough leakage test voltages. Whereas the gray (newer) units may be VERY far off and also need the two 10mfd power supply filters replaced immediately. My guess is that the older stuff was being put together out of WW2 surplus parts that were made far better than peace time parts for sale to non government business's would ever be. Beyond that I haven't a clue...
