The PHILCO Phorum

Morning, I have a Westinghouse WR12X5   http://www.nostalgiaair.org/pagesbymodel...024342.pdf
My questions concern the first 2 items on the  alignment procedure. They are 
IF grid - is that 12SK7 pin 4?
1st Det grid - is that pin 4 or 5?

Thanks Eric

Hi Eric, I put the schematic up again it won't link if its on a line with other words.

IF grid is pin 4 of the 12SK7

1st detector (mixer) grid is pin 8 of the 12SA7 

Thanks for the info on posting links, No wonder it wouldn't come in on the 12SA7 will try it this afternoon. 
Thanks!
