Yes Ron your right that #2 grid does have b+ on it. It's not AVC and it has a .047uf on it.

I can never get the names right. Let see there is control grid, screen grid, accelerator grid, suppressor grid, and on the 6A7 there are a couple more.

So It looks like this radio is a hybrid between the 650 and the 655. It has the RF selector section of the 650 with the IF and detector section of the 655.
!!!!!!!!!!!!!!!!!!!RESISTANCE IS FUTILE!!!!!!!!!!!!!!!!!!!!!!
