Depends on the condition of the old one. I don't know if Eimac is making
them any different than they used to. I would suppose they are about the
same today as yesterday.
Mine still does about 2000 watts with about 100 watts drive which is what a
new tube gets out in the same HENRY 3K Premier amp that is made today.
