I have this RCA Q-103, http://www.nostalgiaair.org/pagesbymodel...015596.pdf The correct schematic is the one on top for the Q103

And I have a question on the alignment page 16-11 the chart on the right hand side for the Q-103.
#1 12SK7 IF grid? Do they mean pin 2,4 or pin 6? I think 6?
#2 12SA7 1st Dect grid. Do they mean 1,4,5 or pin 8? I think 4?

Thanks Eric
