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.
Model codes beginning with a 0, for example the model 051, are Osram valve versions of the model without the leading 0. Technically the 0 should be an O (for Osram), however the digit 0 was used throughout the site before this fact was discovered.
The E suffix indicates a magic eye option is fitted (in models which were available with or without, such as the model 25).
A and B suffixes appear to be simply updates to the current model, R also appears to be simply an updated model ('R'edesign, perhaps?)
P indicates either a permanent magnet speaker version of a model which also came with an electromagnet speaker (the model 26 for example), or a portable model (like the model 694P).
N and M indicated miniature valve versions of a model which started with all (or a mix, ie: model 5) of larger valves. One of these two codes may indicate a transitional mixture of octal and miniature - clarification is required.
S often indicates a stereo model.
Finally, other suffixes and prefixes make occasional appearances in the RCNZ lineup - like the 66W (a variant of the long-running model 66) and the 75XA (a 10-valve version of the model 75 with a separate amplifier chassis).
