I had a Heathkit 100-in-1 (or some such) kit with
the spring clips for wiring, and enough components
to make several different AM radios (crystal detector,
one transistor, two transistor, woo-hoo!).
I remember seeing more modern versions (mine
was late '60s vintage as was my childhood) where
the variable inductor and fixed capacitors had been
traded for variable cap (standard radio type) and
fixed ferrite bar which I imagine also acted as a
minimal antenna.
Of course radios of industrial interest have moved
far along from what was possible here. But a look
at one kit's parts list would lead you directly to a
Digi-Key BOM that costs very little. The value was
all in the instructions (and, back in the day, a full
lack of consumer-facing electronics distributors;
maybe Jameco and Poly-Paks in the back of
Radio Electronics and Popular Electronics, send
for free catalog and wait some weeks for satisfaction).
Speaking of which, you might find better traction
by looking at back issues listings (way back, if you
like projects suited to primitive methods).
I would not focus on the "easy wiring" with spring
clips and all, that has trivial value (developing a
bit of soldering skill would be worth more in the
long run and make it less of a "color by numbers"
exercise). But you could, I'm sure, find spring loaded
test-point components that would do the same job.
