PACIFIC 7 VALVE DUAL WAVE (1935)

The Pacific 7 Valve Dual Wave was manufactured for Pacific Radio Co. by Radio Corporation of New Zealand Ltd in 1935.

The 7-valve dual wave chassis is equivalent to a Courtenay model 11 - and has all of its features but is painted metallic gold.  Normally seen in consoles, but the model seen here is the Pacific Nottingham

Valves (7): 6D6, 6A7, 6D6, 6D6, 75, 42, 80

Intermediate Frequency: 465kc/s

Frequency Bands: 2

Note the use of a rubber-mounted RF / Osc. sub-chassis.  This innovation was obviously not worth the effort as this was the only model to use it.  Interestingly Philco implemented a similar idea in 1937/38 in a more elaborate fashion.

2 versions of the chassis exist

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).

All documented models using this chassis (2 in total)
