I've cleaned these mirrors with soap and water, I even removed the silvering on one and it was really tough to do, that said it will depend on what condition it's in to begin with.

Tom, I skimmed this thread and apologize if I missed the answer. But... is it possible to look directly at the CRT and determine if the picture is in good linearity? I realise that may be a pain to remove or whatever. I just wonder if viewing that picture directly may save a lot of headaches in the process.

Sorry if I am asking the obvious. I really want this to be another success for you!

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 . . . ?

If there wuz anything to the Xray scare, all my kids should have two heads and six fingers.
