I knew someone who was an engineer at Zenith, and he told about the cause of reliability problems with such ICs. Seems the assembly line workers were using a rubber mallet to plug the ICs in the tube socket, and the ICs would suffer momentary stresses when they did that. and those stresses would create small cracks which would let moisture and whatnot in, eventually ruining the IC.
