6-valve dual-wave radio (bandspread). Last of the wartime models before restrictions kicked in.
One of RCNZ's longest-running models (alongside the model 75) - although this was partly due to the war suspending domestic production.
Available in many different cabinet styles, the most common being the Warrior table model
Also subject to many modifications over its life. This version covers the 66, 66E and 66J. See the model 66A for that and the 66W. Model 66R is unknown at the stage, possibly a radiogram version?
a 5-valve version (the model 56) was produced although it does not seem to have been nearly as popular or long-lived.
Intermediate Frequency: 455kc/s
Frequency Bands: 2

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.
