There are some projects in the 1960s ARRL Handbooks that might
be of interest to you. I don't recall any 2 or 3 tube designs,
but I do remember some 4 and 5 tubers, all single-conversion
superhets. If you don't have any older Handbooks of your own,
you may find them at your public library.

There's a neat old project book from the late 1960s called "104
Ham Radio Projects for Novice and Technician", published by TAB
Books, which has a couple of simple regen receiver projects in
it. I see that book for sale from time to time on eBay, and
it's definitely worth having if you like to tinker with small
tube projects.
