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

One version of the chassis needs to be removed to tune the pushbuttons, the other version has extension shafts that extend out the back of the chassis, like the model 65, so they can be retuned easily.

General Construction Notes for Radio Corporation of New Zealand Ltd: The first digit of the serial number typically indicates the year of manufacture of RCNZ chassis' (although not the decade - that requires a little knowledge of the valves, construction, etc). Sets from around 1934 onwards were often (but not always) constructed in a distinctive pressed 'baking pan' style chassis, seemingly unique to RCNZ.

All documented models using this chassis (2 in total)
