Later superhets utilized tubes that eliminated the requirement for an RF amp tube/xfrmr. Older sets had an RF amp both to increase sensitivity and to reject image. Of course there were sets that still utilized an RF amp, usually in the form of a 58, 78, 6K7 or 6L7 tube.

That being said, sets that employ two (or more, like Scott) stages of IF amplification tend to be better receivers.
