If you could explain why you need to remove the part, someone may be able to suggest a way to fix the problem
I believe that the 6105 tubes are not designed to be removed. Randall Benson can replace them, but it is very delicate and skillfull work. I think the old tube has to be drilled out, and then a new thread is cut into the case, and then a non Seiko tube is screwed into the case.
