Excellent suggestion Mondial!  I set the dial on the 38-690 to 600kc, and my digital radio picks up the oscillator at 1070kc, confirming proper oscillator frequency.
Any ideas on what to look for in the IF section? If I am understanding, it cannot be anything past the mixer. All of the IF coils had continuity and I replaced all the paper capacitors (none of the mica), and all resistors are in spec.
