Also in the Set G1 Voltage position the G1 adjustment knob should swing the meter through it's entire range.

BUT, I would be more concerned about any strange odor coming from the unit as this may indicate a power transformer failing.
I think you'll be pretty safe buying one since CRT checkers are something you don't use everyday. CRTs have gotten better in recent years (the last 20 or so) and most set problems are PS or sweep related. So CRT checkers don't get a lot of use.
But ask the seller how many adapters comes with it. I've made about half of mine when computer CRTs started coming out.
