Chassis Notes(most schematics can be clicked to download a full size version) The model 8 chassis was Radio Corp NZ's standard AC mains 6-valve broadcast and short-wave receiver chassis for 1935. Early versions appear identical to the model 108 (predecessor of the model 8) but with 6-volt valves as per the Pacific '108' (the 6-valve dual-wave) - this is probably a case of the factory using up old stock chassis' before building new ones.
This is likely one of the first 'unified' chassis models where all brands got the same chassis with just their badge on the back to differentiate them (Previously different brands had their own peculiarities like painted chassis' or different valves and/or circuitry). Known to have been produced for Courtenay, probably also released under Stella, Pacific and CQ brands.

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. It can also indicate 'self-biased' in the transition period between back-biased and self biased sets where there were models with both methods employed (53S for example)
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).
