I've acquired a sad example of what looks like being a rare beast.

It looks like it was Thorn Australia's successor to the R2 hybrid chassis.
It's all solid state. Philips deflection components, TBA440 in the IF, TBA120 in the sound.
It's in a 17"portable branded "Baird" (ex Radio Rentals) and it uses the same physical footprint as the hybrid R2.

I checked with the knowledgeable UK site respondents and it's not even remotely like a UK Thorn design. As far as I can tell it bears some resemblance circuit-wise to the Philips C1 which of course was designed by Pye.

This must have been released right at the death knock of B&W TV in Oz.

Now in the early - mid 70s I used to service this stuff when they were new and under warranty. Pye, Philips and Kriesler all had similar designs to this one and I saw them all.

But I have NEVER seen one of these before!

Anyone got a circuit??

It appears to be the AWA, Thorn large screen , "T Series T.V. chassis."

I will try to send you some photos of the service manual.

Thanks Wayne! Very much appreciated!

My email is as listed on this site, my old one is no longer active. Whatever you send to it just falls into a bit bucket, no error messages.

Wayne sent me that circuit - thanks mate!

It has aroused some interest on the UK site, Ex Thorn employees say they don't know it. So it is definitely a local effort.
As one guy said "I see no Thorn brushstrokes in that circuit".

It is a lot like a Philips C1 though, as I thought.

Currently I'm waiting on some HV diodes to replace the selenium stick rectifier, which has failed and melted its mounting insulator.

The CRT is a UK made Ediswan A44-120X/R. Otherwise known as Mazda. Not often seen in Oz.

Mazda CRTs don't enjoy a good reputation in the UK so I wasn't expecting much when I hooked it up to another chassis to assess its condition. This would have determined the fate of the whole TV if it had been bad.

Despite the fact that this TV looks very high hours internally (it takes a long time to discolour the PCB that much around hot resistors and the dirt is heavily encrusted) the CRT came up nice and bright!

So I'll pull the speaker and hit it with the pressure washer. Looks like, as a rare set (only T series I've ever seen) it will be a keeper.
