Joe;
  I've seen that trick that they used in your 40-201 used in a few radios, such as in a Canadian RCA Victor A-30, in a Fada model 1001 that I own. What is interesting is that the A-30 also has five bands with this broad tuned RF amp, but it's larger brother the A-22 has six bands, and a tuned RF amplifier stage, and a magic eye. I have electrically restored both the A-30 and the A-22 and can't really figure out why they would use a tuned RF amplifier stage in one set but not the other, I haven't really noticed much difference in performance, though maybe it helps on short wave for selectivity? There is one model below the A-30 that I have yet to own, it's called an A-24, it has four bands rather then the five of the A-30, but the same broad tuned RF amplifier stage of the A-30, also six tubes, and all three sets that I mentioned have a pushbutton bank of six buttons. Oddly enough there does not appear to be a table version of an A-30 (or A-37 for the following year) and no console version of an A-24, but there is of the A-22 and A-23, product planning in the radio industry was strange.
