When the CRT is in the optical box, you can only view the CRT face from the side:



But if you remove the entire tailpiece assembly, you could view the CRT face fully:



I'm concerned about X-rays in that scenario. At 25KV, X-rays are a factor, so would you get fried if you view the CRT outside the metal box?

Somewhere, I saw a statement from bandersen that more X-rays are generated from HV rectifier tubes than the CRT itself. Can anyone verify that? In this set, the HV rectifiers are sealed in their own little metal box, so if the CRT itself isn't a big emitter, maybe viewing it outside its box wouldn't be so dangerous . . . ?
