Andy.........I used the wrong wording "the 6BD4 HV reg was running dark as expected" in describing the glow reflected from the tube's plate when running the CRT at max HV of 34KV. Obviously, it was pulling far less current and glowed less bright than it did at minimum HV setting of less than 25KV. This is typical of all shunt regulators. At all settings, it glowed brighter when the screen went black as it should.

My main concern is how much X-Ray did I absorb during the year of running 34KV with no CRT safety glass or cabinet screen glass? Is there any documented evidence that 21in CRTs running above 30KV has resulted in injury to those persons working in close proximity for extended periods of time? If so, what was the symptoms, and prognosis?
