Well, my experience is quite different I must say. My Coincident Frankenstein MK II mono block 300b SET has output transformers. Over the years I have had the opportunity to use a wide variety of 300b tubes.
Elrog
EML XLS
EML Mesh plate (a legitimate "mesh plate")
KR XLS
Takatsuki
Shuguang black Treasure
Western Electric Reissue (1990s)
Electric Harmonic
Sophia Royal Princess
Sophia Mesh plate (actually a perforated plate, not a true mesh).
With my system I could very easily and pretty quickly discern and hear distinctions (subtle and not so subtle) amongst all of this tubes. Each one of them clearly has their own unique sonic character.
BTW my system utilizes the Coincident Statement Line Stage which has transformer volume controls. What 300b OTL amplifiers are available?
