Ok I know that some will say its not worth it before I begin! I was wondering when adding the 2nd mosfet to a 949/959.... On cbtricks its going off of the 1969 version it really doesn't show biasing the 2nd mosfet with a companion part. Wouldn't it need the same biasing. Just curios!!! Now I am working with the mosfet edition already, so I'm assuming I could shadow the parts as in the single final stage.. Thank you for all help. I am trying to understand more about how these things work..
