Despite the fact that Pathé often used generic parts, it must be considered a major brand based on two attributes that are far more important than the source of its parts: number sold (as evidenced by number of survivors today), and how long the talking machine brand was manufactured.
I suggest a simple definition: if a talking machine whose brand name is commonly or even occasionally found today in a global market, and the brand was manufactured for at least 8-10 years, I'd consider it a major brand. All others are off brands. (An obvious exception would be U.S. Berliner, so I'll weasel and say that Berliner, Johnson, and Victor are all the same "brand...")
I get the feeling that some believe the term "off brand" somehow carries a negative connotation. That's clearly not accurate, as the Vitaphone, United States Talking Machine, Multiphone, Autophone multi-selector machines, Greenhill, Echophone, and others are highly sought-after talking machines - - and are all off brands. The Victrola XI is, of course, from a major brand. Which would you rather have?
