"Did Mullard have a factory in Holland"By the 1930's Mullard was bought out by Philips. After that Mullard was just one of many brand names used by Philips.
Philips had factories in England and in Holland and many other places.
The tubes made in England were normally labeled Mullard. But not always.
The tubes made in Holland were normally labeled Amperex. But not always.
Tubes made in any of the Philips plants could be labeled anything. Mullard, Valvo, Amperex, Siemens, Miniwatt, Mazda and others.
The codes tell you which of the Philips factories the tubes were made in.
