Pin 2 of the 7C6* though a cap and then pin 3 on the 7C6. Next will need to set the sg to produce a rf signal. Set frequency range on B and adjust dial for 455KC. Turn up the attenuator Apply signal to pin6 of the 7B7 closest to the 7C6. Do like wise with the other 7B7. Next *pin 2 of the XXL closest to the IF transformer and pin 6 also . If all is well you should hear a 400cy tone when connecting to these points. *Be careful some of these point have HV connected to them.
