Hi I bought a Stella 5D 3 years ago and would like some more info, and possibly a circuit. What I do know is it was made in 1935 by Radio Corp NZ. It has this valve line up, 80 42 6B7 6D6 ECH35 Im pretty sure the ECH35 is a substitute as I believe they weren't available until 1939 It is working, being an old resto going on the sticker someone has put on the back of the cabinet.
Im in Australia but I have about 5 NZ radios, Info on these sets over here can be hard to get.
Hi Ben, the standard valve lineup at that time for a 5-valve with 6.3V valves was 6A7, 6D6, 6B7, 42, 80 - and the only cabinet label I have an image of is from a 7D - it might help, but probably not... here it is anyway.
If its a broadcast only set (I don't know the 5D, sorry - no circuit and I've never seen pics - although if you want to contribute some to vintageradio.co.nz they'd be appreciated) then it might be similar to the early model 15 circuit (check vintageradio.co.nz for that) - having said that, they came in around 1936, and Stella had a 15 in their lineup, so it might be something else...
Is it dual-wave? I'm guessing it is and thats what the D is for... The model 21 was a 5v dw set but too late, it uses octals. It could be a 109? Check www.vintageradio.co.nz/model/courtenay/109 and compare the chassis - RCNZ released sets that were electrically identical except the transformer heater winding and the valve lineup - Pacific 6-valve dual-wave and Courtenay 108 being a prime example - both identical electrically but the Pacific used 6v valves and the Courtenay used 2.5v
Hopefully that gets you on the right track.
There are no personal problems that can't be solved with the liberal application of high explosives
Hey Steve, the 109 chassis looks very similar to my 5D. To be honest I dont know if its dual wave. I might pull the chassis and investigate more. I emailed you a couple of photos for your site, let me know if you dont get them, or want more
