(I don't have the schematic.) The tuner may or may not have a mixer plate coil adjustment. If there is, it may have some effect on the IF response curve.
Crist, was there a particular reason you opted to do an IF alignment?

Yes, I wanted to learn how it was done. After replacing all the caps and resistors I thought it could use it.
