I just completed restoration of a Philco 16B, which has 2 stages of tuned IF amplification but NO RF amplifier. I am not impressed with its sensitivity - nothing to write home about. This is subjective, of course, since I have NOT tested the radio side by side with other radios using the same antenna, etc. But I feel my Zenith 8S661 and 9S367 both outperform it. Both Zeniths use external antennas and have a tuned RF amplifier and only one stage of IF amplification.

This may not be a fair comparison though, since the Zeniths are later technology.
