Bill,
These sets are a bit tricky to align properly, and if not done right, you won't have any low end at all.
You pretty much have to ignore the dial calibration on the low end of the dial. Set your signal generator to 600 KHz then find the signal on the radio. Once you find it, you need to tweak the outer rotor plates on the antenna section. By pulling the cutout sections out a bit or pushing them in a bit, you'll change the resonance of the antenna section to bring it into alignment with the LO. Then use the trimmer on the tuner to bring both the LO and Antenna to match the dial at about 1400 KHz. You may have to do this several times.
