It sounds like there is enough gain. So it seems likely the antenna transformer is not working well. 

Poke around there and see if you can find something wrong. Try the antenna wire on the grid of the RF.
You should get lots of noise or maybe even be able to tune in a station.

As to your original question the AVC line at the band switches is where the b line and the d line come together through R6
!!!!!!!!!!!!!!!!!!!RESISTANCE IS FUTILE!!!!!!!!!!!!!!!!!!!!!!
