[Amps] 4 x GU-81 Grounded Grid Penthodes

[Máximo EA1DDO_HK1H]

Hi all,

I am already starting this project.

Just a begginers question.

Remember it is 4 x GU81 Grounded grid.
Filament transformer. It is 12.6VAC around 11A each tube. Should I use one transformer per tube? or Can I use one transformer per two tubes?
(One for all four tubes is too big 45A)

Thank you
