Well what's interesting is that the 1st IF can's IF Frequency is 10 KC lower than the original IF Frequency, and the 2nd IF can's IF Frequency is 10 KC higher than the original IF Frequency of 465 kHz, which I'm not sure what the point of that would of been but its kind of bizarre.

And I guess I can see what happens as far as trying to align the IF cans to the original 465 kHz IF Frequency.
