Default Re: Grundig TK24 mystery substance

It's impossible to say what the composition is of a manufactured board product without having it tested. It is likely to be an ACM from its appearance, and the fact that when the machine was made, such products were thought to be the best for the job. If an ACM, the level of risk it poses again cannot be guessed at without testing which kind(s) of asbestos are present. Personally, I note such things in my register and leave them alone. Many museums seal the product if temperature range does not exceed the limits of the sealant, e.g. in static exhibits.
