Radionics, was what I had, this was a large Perspex sheet like a pegboard
with a leg on each corner, indeed there were two. All the components were
mounted on plastic bases with 6ba brass studs that went through the holes in
the peg board, and were connected by various lengths of brass strip using
nuts. If you needed to hop over, simply use the top of the pegboard.
It took you all the way from Crystal set to superhet with push pull output
stage, and all the way from simple gates to binary arithmetic using small
torch bulbs in bistable circuits linked to do the division.

I even made an am radio transmitter for medium wave which modulated a driver
stage and hence did not fm. I had to get some custom bits put together like
power transistors on bases of course for the latter, but hi is was in the
days of germanium so accidents did happen due to finger trouble with the
brass strip wiring, but it thought me a lot. Even though it was big, I could
make a circuit with an OC170 that could receive air band signals, it was as
wide open as a barn door, selectivity whats that? Grin.

Does anyone here remember what was the precursor
to the Philips Radionic series?

I am thinking of about 1963 which is a few years
before the Philips X20 et seq came about.

I lusted after one of those kits but with 5 of us
brothers and sisters, the Xmas budget limited
each of us to Xmas presents costing £1 only and the electronics kit
was about £3.
