Sounds like you still need alignment. Or the oscillator could be off. Use 455 on the Sig Gen for that.
Most alignment guides say to start at the last IF coil first and then work backward. try to hook an ACVTVM across the voice coil and turn the radio all the way up, controlling the volume with the output of the generator. Make sure you're not using a metal screwdriver. Align for 1600 first, then 600. Then go back over it all again.
Hope this helps-
