It's an Ambassador 455KC REPLACEMENT! It seems you may have a lead on this problem. I still have to wonder why the 10.7MHZ was too low also. The radio has another different brand IF in it. A RI-Tran. It's a mess also so sweeping it may not give any leads. I guess another question is, has anyone swept a IF out of the circuit and had it pass 455KHZ as it should?
This radio has double foil boards and is requires real care not to damage the PC board.

How are you connecting the IF transformer to your test equipment? You could be adding capacitance to it from the cables and such.
