I think the Radionics company in Three Bridges made my brass strip one and
it was hard wearing. Tandy used to sell a breadboarding system with springs,
but they were notorious for bad connections and crackling.

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.

I seem to remember the can type transistors in these sets had "fragile"
legs not really designed for reinserting in the springs used as
connectors.
A leg would break off and they were very expensive to replace.
