The Bell Cavalier was manufactured by Bell Radio-Television Corporation Ltd in 1967.
5-valve broadcast band stereogram.
Actually only 4 valves, although it uses multi-purpose valves throughout and a diode bridge rectifier rather than a rectifier valve, so its more like the equivalent of 7 or 8 valves.

Chassis Notes(most schematics can be clicked to download a full size version)
A number of models used this chassis in the late 60's - if you have a Bell stereogram have a look at the chassis and see if it matches this chassis layout.
A higher res copy of the schematic can be downloaded here - unfortunately the original is blurry so some of the details are difficult to make out.
