The 1960 variant of the Bell Colt.
Several different dial glasses seen, and it can be hard to identify. It might have been the first model to use the newer push-on knobs and might also have been the first model Teevee Radio produced for Bell.
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.
The radios in this series are:
Intermediate Frequency: 455kc/s
Frequency Bands: 1
Chassis Notes(most schematics can be clicked to download a full size version)
The only previously known schematic appears wrong when compared with 1960 models, but there may be significant differences between models as this was around the time Teevee Radio were producing Colts. The hand-drawn schematic was reverse-engineered from an example but your mileage may vary. Please make contact with any noted differences that appear to be factory done.
