Honestly, I never understood the debate over a sheet of asbestos in an old radio. I just leave it where it is. Unless you decide to gnaw on it or rub your face in it, it's hardly threatening. I remember a video of an old man in South America that hand made brake pads with a raw asbestos. No mask, no gloves. If he made it to that old age in those extreme conditions, I think we're okay with our old radios.

Well, yes, the whole asbestos thing is WAY overblown. Still, I don't think I'd be terribly comfortable with a crumbly old asbestos sheet being placed in the thermal air stream of a radio I might be using in my home. I'd have no problem pulling it out and throwing it away. Breathing in a pinch of asbestos dust for one minute is not how you die from it. Having it in a working radio in your home where it *might* blow a bit of dust off a few days a week - eh... Having snowball fights with the stuff while not wearing any kind of mask, every day for 30 years - now that's how it gets you.
