For a green stripe MK III
Class A = 25 watts (tubes wired in pentode)
Simul-Class = 85 watts
Simul-Class watts are the sum of the outer pair of tubes (class A) 25 watts plus the inner pair (class AB) 60 watts. So 60 plus 25 is 85 watts total power in simul-class mode.
The no stripe through blue stripe versions of the MK III are 10 watts less in class A mode due to the outer pair of tubes being wired in triode. So you have 15 watts class A 75 watts in simul-class.
