el34 heater 760 ma X 2 plus 300 ma for 12ax7 run in pllel gives 1820 ma so 2 amp would work ok but I like to spec a little over as 10% would put you right on the limit. 3 amp would be better as this is 30% over rated.
Just remember you will need a 2amp 5 volt heater winding for the 5r4 as well. I would give it 2.5 amp here.
