The Courtenay model 11 was manufactured for Turnbull & Jones Ltd by Radio Corporation of New Zealand Ltd in 1935.

7-valve dual-wave set.  Also found in Pacific trim as the "7-Valve Dual-Wave".

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

Intermediate Frequency: 465kc/s

Chassis Notes (most schematics can be clicked to download a full size version): 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.

All documented models using this chassis (2 in total)
