The Bell Colt Cadet was manufactured by Bell Radio-Television Corporation Ltd in about 1957.
This model is part of the Bell Colt series of radios.
The cadet is a budget permeability-tuned 3-valve model - easy to spot because in place of the usual tuning gang are two metallic tubes.
Estimated introduction date - 1957
This appears to have been followed by the Champ, also a 3-valve but with a traditional tuning gang.The Bell Colt Cadet is part of the Bell Colt series of radios.
Bell Colts ran from 1951 through until 1980 - the longest running model of NZ built domestic radio. It saw many different engineering changes over the years, and the last few models dropped valves in favour of new transistor technology.
