BELL COLT 5B5 (1955)

The Bell Colt 5B5 was manufactured by Bell Radio-Television Corporation Ltd in 1955, it was in production for 2 years. It's part of the Bell Colt series.

Third model of Colt.  Some have 5B5 stamped on the chassis, some do not.  This was the last model of Colt to have the code stamped on the chassis though.  One sighted example just has B5 stamped on it.


The Bell Colt 5B5 is part of the 'Bell Colt' series.

There is considerable information on the main Bell Colt page about this long-running Kiwi icon.


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.

Please note that not all radios shown in this series were known as Colt's - the Planet, the Mercury etc were models in their own right - but they have a Colt chassis in them and so are included here as part of the wider Bell Colt dynasty.

The items in this series are

Chassis Notes(most schematics can be clicked to download a full size version)

This schematic was modified from a Bell factory schematic for the model 5B4 Colt.  The chassis layout has been corrected as the 5B4 one is wildly wrong, and the component and circuitry changes have been made using the original drawing.  It should be correct as it was drawn by reverse engineering an existing set, but the usual disclaimers apply - E&OE... any corrections would be appreciated.
