No leakage (G1) or heater-cathode leakage is indicative of a good CRT. I've seen only a few (out of many hundreds tested) that had any leakage. I own 4 B&K 470s, one is my original from the early 90s, and three were passed on to me when my dad died. All 4 had the crappy plastic case hinge fail - I use a piano hinge and some self-tapping screws to replace it. The latches on three are also broken - Velcro cloth and some rubber cement fixed that.
As long as you can set the line adjust, G1 and G2's, and your CRT shows emission, I'd say you have a good 470. They are workhorses. Cheers,
