I have a Techtronix type 544 oscilloscope thing is a beast weighs like 100 pounds has like 10 ECC88 tubes in it, my main concern is that the huge fan on the back of it has this black air filter, and it basically crumbed everywhere. The filter just fell apart into like almost dust, and I want to make sure that this doesn't contain asbestos?
My 544 scope had a dark grey plastic foam air filter, had to remove and wash out the dust from time to time as it became clogged, no sign of asbestos in any of the Techtronix scopes I have used.
Thanks, yeah this is the original I think it was never changed, hence the reason it crumbled, its black/gray could have been foam at one point but no telling with it crumbled haha
