The only real problem is getting the tube out. Once it's out,
getting the stuff off of it and the cylinder it was in is no problem,
the adhesion is not very strong, just enough that you can't push the
tube out without likely smashing it.

So do it the way a capacitor is removed from the PFN for the SSY-1. Use a
fast cutting disk, or slow hacksaw, to cut the outer cylinder parallel to
axis, peel it back enough to remove the innards, then peel the gunk off the
internal cylinder (cap, or laser in this case).
