Are you sure 6A7 is good?
Increase your IF signal a whole lot if possible.
Make sure your cap on your 6A7 soldered well.
Check IF coils for continuity.
Try bypassing 6A7: inject the 460kHz right into the IF xfmr (6A7 plate) via a capacitor and put a Zener in parallel to the generator output to protect it from initial surge of Plate voltage.
PS. Have you UNPLUGGED the Grid Cap wire from 6A7 Grid Cap? If not, it should be unplugged.
