RE: Hope someone can help clear something up for me . . .

The Philips Electronics conglomerate owned several brand names. Amperex and Mullard were among the many brands Philips owned. Point is the name on the tube means very little to nothing. As Peter pointed out, the real story is in the acid etched codes along the bottom shoulder of the tube. Those codes will tell you the what, when and where of each tube.
