Back in the '60s I had a little portable radio that used wire-ended
valves/tubes about half an inch diameter and an inch long.
I had some of those. They were wire-wrapped onto printed circuit
boards which were mounted in lightweight alloy chassis, all made at
Ferranti, supposedly for or from the TSR2.
