Sparton rebuild

Is it the line from the bottom of the two 3.3M resistors (from bottom of the last IF coil) over to the grid of the rf amp (1st tube)?

Ah!, I reviewed another document I have that shows the rf amp and converter stages with the different switch positions and it clearly shows the AVC is applied to the grid of rf stage as I indicated and to the bottom of the tuned circuits for the converter stage. So both 3.3M resistors are involved. So I suppose one would lift the connection of the two 3.3M resistors to the 1st audio stage and apply the 3V there. Sound right? Also why would one not do that during the alignment too? Alignment procedure doesn't even mention AVC.

BTW one of those 3.3M resistors tests correct but one is reading over 4M. I suppose I should replace both huh?
