Chassis Notes (most schematics can be clicked to download a full size version):
The 1934/35 range of Pacific radios were available in 5-, 6-, and 7-valve options (and some versions of battery sets as well). The 5-valve was broadcast-band only, while the 6 and 7 valve models were dual-wave. All were built by Radio Corporation of New Zealand in Wellington.
The most common was the 6-valve dual-wave chassis, in a near-standard 'baking pan' design, with dark metallic gold paint rather than the usual cadmium plating (this was the last year that this chassis colour was used). Also notable were the square 'tabs' on the corners of the chassis rather than the usual rounded corners found from the following year. The 5-valve option was probably similar / the same as the model 15, and the 7-valve is similar to one or other version of the model 11 7-valve chassis.
These were the first mainstream Pacific models with an aero (round) dial.
Electrically they are identical to the Courtenay 108 circuitry. The Courtenay uses 2.5V valves in all sighted models while the Pacific sets uses 2.5V valves only in the earliest examples, with most appearing to be fitted with 6.3V equivalent valves.
A common fault (aside from the usual things like capacitors) in this chassis seems to be the 55 ohm resistor (wirewound on a flat former and soldered to the speaker socket) going open circuit.
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.
