This would be the first time I have seen one of these raise its head in public. Its in Palmy North
They were the top model(?) for the 1939 year, with motorised pushbutton tuning among a raft of other awesome features. I have one in my restoration queue and I'd bid on this one if I was closer... particularly as mine has been attacked very badly by borer... alas, I can not justify driving across the country and across the ditch to get it... I'd be shot by she who must be obeyed! I want it but I hope it will go to another keen Radio Corp-aholic...

Thanks Steve, I wish people would take better photos on trademe, its not hard. Is that a celluloid Dial glass?, it looks like its gone opaque, but you would expect RCNZ top model to have actual glass wouldnt you?

Those are about the worst photos I've ever seen on trade me I think Yes its a plastic dial lens - I think this was the first (or close to the first) model with a slide rule dial as well. The actual dial is behind it though so is likely still ok.

Bad photos on Trademe seem to be the norm! What an interesting set. The use of the side contact EF8 is very unusual, actually I have never come across another use of this valve. Might be a bit hard to come by me thinks.

Ok, you've twisted my arm - I'll restore my 88 next I'm also rethinking not looking at buying this one - maybe a small road trip wouldn't be a bad thing. School holidays soon, and Kaikoura is on the way... fantastic fish'n'chips there...

It is very impressive set from a technical point of view, maybe not the best looking radio Radio Corp ever made. I've never seen one "in the wild" before either. Given its rarity and specs, it definitely belongs with a collector who will give it a proper restoration...like you Steve!
I would love to buy it too, but Palmerston North is a bit far from Dunedin!
We can only hope that the power and output transformers survived the obligatory "turned it on to see if it worked" test.

It would be great to hear the 88 in operation with the switchable selectivity, Ive got a RCNZ model 75 and 90 and they have a nice wideband IF, when "Magic" was still on "702AM" in Auckland, the audio bandwidth was really good

Of all the (working) valve radios I own, my model 90 would have the best sounding set (actually by quite a margin). The first time I powered it up after repairing the burned out transformer and spending hours figuring out how to neatly replace those accursed metal-can oil-filled capacitors that are soldered into cups under the chassis and then used as tie points as well... what was I saying? I get frustrated just thinking about those darned things... oh, yeah... stunning sound. Everyone should own a 90, just for the sound. I have a 91 in a Flotilla radiogram cabinet with a Goodmans(?) 15" speaker but I don't rate it against the standard table-model 90 in the Endeavour cabinet with a 10" RNZ Electromag Speaker. The Flotilla is loud, but it just doesn't sound as good to me... ok, slight detour from the topic there Richard, we had Magic on AM up until recently too - I miss it. At least we still have the Coast at the top of the dial. And Daniel, I'm only a few hours closer than you... Anyway, I'll keep an eye on it - I still need to factor in that I'll be killed to death if the boss finds out I'm even considering it though.

yes the model 90 had negative feedback + tone control from the secondary winding of the output transformer back to the first audio stage, the designers were learning some new techniques to improve the sound quality by that stage.
I was told years ago that Radio Corp back in the day, got a speaker designer over from Jenson Speakers in the USA to design their electrodynamic loudspeakers.somebody may be able to confirm that?

Truth or Myth? I don't know. The problem I have is that I can't work out who J. (Jens) Jensen is. He doesn't look like Peter L Jensen of Jensen Speakers, although allegedly both "were Danish-American engineers who played a prominent part in the invention and development of the modern loudspeaker". One with a great deal of historical fact behind him and the other just according to this page from the model 75 brochure. I heard a rumour that Jens was a brother who had a falling out with the family but I've yet to find anything to back that up... I've only just started digging on that though. Regardless, he was obviously not a fraud because these speakers punch WAAAY above their weight in my book. RNZ also made speakers for Rola, which might explain why some of them look so similar. I've only recently uncovered that, so I want to get some speakers together and have a look at them in more detail. A job for another day though.

You don't have to justify yourself!

Not to you guys I don't - you all understand... but my better 3/4 might need a little justification when I detour half an hour out of the way on the drive home then fill the back of the truck with yet another radio
