Yeah.. Let me ask a stupid question.. When you see a tube diagram in a manual. Are you looking at the tube from the top or bottom?
I works GREAT now Pete. No loading down at all with 70K resistor. I am on 40 AM now at 7293. There was a Sidebander on 7290. I could really see him on the scope. I narrowed down and slid over and he is about gone. Pretty neat.

See 6SA7 tube info:
http://www.mif.pg.gda.pl/homepages/frank/sheets/049/6/6SA7.pdfAbout 1 "page down" click: Base Diagram typically shows a bottom view.
In this picture, if the "key" is facing the lower tube, your connection is on the wrong side.
