I'll talk about lead first because that's what the thread was about.

Glass is a very stable substance and lead will certainly not come out of it to any appreciable extent while just sitting there. As mentioned above, lead crystal is still used for glassware.

The TCLP test is valid only with respect to putting the material in question into a landfill. The leachate the sample is soaked in is sort of a synthetic landfill leachate, with an acid pH. The result of the test tells little to nothing in terms of toxic risk from having the material in your house.

I don't know where mercury would show up in a CRT TV, certainly not in the glass, it's far too volatile unless salts were added to the glass...but why? I just don't know of any mercury in CRT TVs.

As for cloth wire insulation, much of it was cotton, but if you're concerned, I think you can seal it with something. I'm thinking a silicone based waterproofer like Thompson's Water Seal. I think I read that somewhere on a radio forum back in the day. But I haven't messed with any of mine, I just leave them alone. Unless you're breathing large amounts all day long, the risk is small. A radio, I wouldn't worry about.

Jeff, I've seen the 'block' of asbestos I think you're referring to, it's usually a sheet on the inside of the cabinet wherever heat given off by the tubes may damage the finish or overheat the cabinet. Such as over the power tubes. I've seen a foil/asbestos sandwich too. It could be replaced with something else, but I usually just leave it.
