Are All Mullards Created Equal?


I want to upgrade the rectifier tube in a CARY SLP-05. Began a search for Mullard 5AR4, which a majority of you on the site agree are preferable. Is a Mullard a Mullard regardless of who they were built for, manufacturer codes, base color, fat base, metal base, etc, etc? help...

I believe the 5AR4s from the 50s to early 60s, built in England and Holland, are most desirable. Fat base, brown base, and metal base perhaps more so. These will be at a premium, but supposedly, they are indestructible.
