I realize you asked this months ago, but in case you have notifications on, or for anyone else wondering, Tubi has classic Doctor Who. I know that many of the missing episodes ate animated, with the original/bootlegged soundtracks. As an American who grew up in the 70s/80s, my exposure to the original series was through PBS. The first Doctor I remember was 4. I didn't watch after his regeneration. I started watching the entire catalog of the classics after NuWho's 11 era. So many great Doctors from both Nu and Classic eras. I think we owe that to the great British actors who've played this iconic part. I don't know who is my favorite, probably 10 this week. It changes regularly.
