Great shape cosmetically and electronically are two different things. I also picked up a used Hickok (533) a few years back, and had it restored and professionally calibrated. Assuming it uses the same rectifiers, your 600 would use a 83 and a 5Y3 rectifier. First thing I would do is replace the rectifiers with known good ones, and potentially replace any electrolytics while you're underneath it. Then calibrate it or get it calibrated. Get a calibrated reference tube as well. Typically the Hickoks use a 6L6 as their reference calibration tube, although I use a 45 that measures exactly at 100%....
