[Amps] tubes in parallel

Hi Vic,
The reason is laziness:  I already have two hand wound plate chokes that are self resonant at the desired frequency and while they are heavy enough to handle a single tube with some reserve they would not handle two tubes with some reserve.

Probably not, but the really interesting question is "why?"
