I just purchased a Dynaco ST 70 with the Van Alstine super upgrade board.
It was purchased 2nd hand but looks new. I am a newbie to the world of tubes and not very tech oriented. Knowing that, how do I bias the tubes on the st70? I hear about it all the time, basically understand what it is, but have no clue at all as to how it is achieved. Can anyone explain to me how this is done? In the simplest of terms please.
Sorry for the silly question.
thanks
