Have you (or anyone else) come across the
'Improverished Radio
Experimenter' books? THey're fairly modern (in the last 5 years or so),
and describe making valve receivers using this type of construction. The
valves go into those screw-terminal octal sockets normally used for
relays, coils, including the IF transformers are hand-wound on cardboard
tubes, etc). The result is a 3 valve superhet that takes up most of a
desk, but which apparently works.
I seen a few mail order places selling them but I
want to get
"The Voice of the Crystal" -- build everything from scratch.
"Instruments of Amplification" -- build tubes/valves and transistors
from scratch.
I watch a lot of Japanese animation and they often having a si-fi
or alternate history setting have great "what if" inventions or
another version of common place things. If you like older space travel
the Japanese animated movie "The Royal Space Force:The wings of Honneamis"
is one to watch but it may be very hard to find.
