Philco model 60s are not too bad but they still use the typical five tube circuit used in millions of sets right up until the end of the tube era. With a good long wire antenna they can do fairly well, but not as well as a set with a tuned RF amplifier stage, or even one with an extra IF amplifier, I'm not knocking it just stating that it has it's limitations. Actually I think that the main issue in the Northeastern states isn't sensitivity it would be selectivity. There were also some sets that had an untuned RF amplifier stage, so they had the extra gain, but not the extra selectivity, I think that is what you might get with many of these aftermarket loop antennas so read the fine print.
