At first glance the underside of that chassis just doesn't look like a commercially manufactured set. Either it's had a lot of work done at some time or I wonder if it might have been a kit chassis.

I've been having a similar problem identifying a stereo valve amplifier/tuner given to me recently and have concluded it was probably a kit with very little chance of finding a circuit. A shame because I don't imagine too many stereo valve amps were made.

Cheers,

Warren

It is missing an ARTS&P sticker which could indicate it being a kitset. I'm not sure how it worked in regards to licences for home-built radios in those days.

Valve stereos were fairly common throughout the 1960's. If yours is indeed a kit-set and was locally made, it would most likely be based on a Radio Television & Hobbies (RTVH) or Mullard design.

I'm not sure how it worked in regards to licences for home-built radios in those days.

Home-brewed gear was exempt from payment of patent royalties so the ARTS&P transfer was not installed on such gear though a listener's licence was still required.

AWA and Philips, along with their affiliates, were amongst the major players in the ARTS&P scheme so when you bought their valves to run your kit they still got some benefit anyway.

A valve a day keeps the transistor away...

Hey all
Just posting as an update on the radio I finally got to look at the radio in more detail and replaced all the valves with the lineup suggested by monochrome as I had a few dead valves and put a few new old stock ones in. Then I went on as Marcc suggested and put a 3.5 ohm perm magnet speaker over the output and plugged the baby in and worked like a charm.

I punched the valve line up on radio museum and found a few possible suspects from brands:
Bland radio ltd Adelaide
British general electronic Sydney
Kriesler Sydney
Southern Cross radio Sydney
Thom & Smith,Tasma Mascot
Windsor Sydney

The only problem is that it has so much volume I have to turn it the slightest and it will come beaming out but have barely turned the volume control any advice?

The next stage for the radiogram is to get a new cabinet as I will never find what it actually goes into I will attempt to build a cabinet that will do it some justice to display this piece of history.

And I just want to say thanks to everyone for helping me identify the radio and get it working again
