[HomeBrew] Need minimal current for 6AG7/6l6 transmitter

[n6kyr at netzero.net]

Can anyone tell me what the minumum tranformer current rating ought to be for a 6AG7/6L6 MOPA? 
I suspect around 125-150 mA (but I just wanted an alibi on this). I do have a surplus military grade 320 VAC 100 mA transformer that I can use in full wave bridge s/s configuration. If I'm also correct, much of this military stuff has been deliberately derated or over engineered.
Let me know your thoughts. Cal, n6kYR/8
