In GAOR John Stokes tells us (page 65 ) that Radio Corp NZ produced only one car radio - the MC7 in 1946 , which he did not feel was exactly a triumph of radio design. However I have a set MC8 ,its model number clearly engraved on the brass plate.This set goes, (perhaps it also was less than a triumph etc) but in my view not well enough. Can anyone shed any light on this and does anyone have the circuit for it? I would like to have a go at re - tweaking it. NZVRS Library do not have the circuit.
Howdy Trombone, the only reference I've ever seen to the MC8 is in JWS's list of Columbus and Courtenay models - he lists it as a 1951 model but shows no more details so it sounds like he later became aware of it. I also have service dept notes from RCNZ (but not schematics) for later models (506 and 512) from around 1954/55... they refer to a problem where, I quote: "The sensitivity and signal-to-noise ratio of these two models has not been of a high standard" and have replacement coils
I have an advertisement, drawings (main schematic DWG362) and the lab notes for the MC7 - I wonder how different they are? Given how bad JWS seems to think it was I imagine they had quite a redesign... or maybe they didn't so the MC8 was short-lived? The MC7 advert was in the December 1947 copy of The Listener... maybe there could be adverts in the December 1951 / Jan 1952 Listener for the MC8? I don't have any Listeners from that period. Of course that won't help with service info, but it might be interesting to find.
Would it be possible to get photos of your set to use on vintageradio.co.nz?
There are no personal problems that can't be solved with the liberal application of high explosives
Hi Steve,Thanks for the reply.It clears up several points at once.I wonder what the special replacement coils were.If you would like to photograph the set drop by Lees Rd (yes , near Pineacres)sometime these holidays if you are about. There is another set I have which we spoke about which I think you were keen to photo as well. Ring first to check I'm home.Cheers, Trombone
