PACIFIC MODEL 15 (1935)

The Pacific model 15 was manufactured for Pacific Radio Company Ltd by Radio Corporation of New Zealand Ltd in 1935, it was in production for about 2 years. It's part of the 1935 Pacific series.

Other radios based on the same chassis:

Pacific 5-valve broadcast-band radio.

Three cabinets seen, one like the earlier model 105, one similar to the Courtenay 15 and the other like a simplified version of the Pacific 'Carmen' cabinet from 1934/35.

The Pacific model 15 is part of the '1935 Pacific' series.

There were 7 main models of radio released by Pacific Radio Co. in 1935, or to be more precise there were 3 models of AC mains chassis (and several battery and vibrator models), fitted to one of 7 main cabinet styles (with the occasional oddball showing up in the mix). 

The predominant chassis was the 6-valve dual-wave, with a 7-valve dual wave and a 5-valve broadcast version available as well.

The items in this series are

The model 15 chassis was Radio Corp NZ's standard AC mains 5-valve broadcast-only receiver chassis for 1935. 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, Stella, Pacific and CQ.

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).  This suffix was used in the mid 50's when Radio Corp was changing over.

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).

Model nicknames are often sourced from either newspaper advertising, company literature or the NZ Radio Traders Federation official trade-in price books (Particularly Courtenay models from this publication)

In 1954, model numbering changed, to begin with the number of valves (ie: 501 - 5 valves, 1006 - 10 valves, etc) although the final 2 digits don't appear to have much significance.  Middle digits of 5 (portable) or 6 (mantle, including clock radio) are used on the AWA-designed plastic-cased sets.
