I am seeking information,any information, on the Tyne brand colour television.
I have only ever seen one here in Australia.

It had the general layout of the Thorn 3504 chassis, but was distinguished by its use of a welded aluminium frame to which the circuit boards were fitted.
I believe that it was made by Derrick Tyne.

During the mid 1970's there were many importers on the bandwagon, importing sets during the colour TV gold rush.

Who has in their collection an ASA CTV, a Blaupunkt/Siemens CTV, a Finlux, a Radiomarelli, Luxor, or even the little bullet proof 18" General CTV?

Photo's please.

By the way. Why isn't there a forum for colour TV's.? Old B&W TV's have one. If these old colour TV's were cars, they would be considered as classics and have Historical Registration. Why are old CTV's not given the same reverence and their own forum?

Please, I would really like to learn about the Tyne. History, schematics, photographs etc

I've never seen one and I'm doubting I ever will, as they were not a common set even when new.

They were imported from the UK from a small TV manufacturing business run by Derek Tyne. He died several years ago and the brand has almost been forgotten in the UK. Derek has a daughter living in Australia who claims to still have a Tyne TV. It may well be the last of it's kind.

I did manage to acquire some parts for one recently and I'll post pictures of them in the next day or two. I'll also post the circuit diagram when I do the pictures.

In the meantime here is an advertisement for an Australian Tyne and a picture of Derek Tyne.

The colour TV's are welcome in the Vintage TV forum despite the description mentioning B&W TV's only! As for the other brands you mentioned, I have most of them apart from the ASA (still looking) and the Radiomarelli.

Yep, all televisions are welcome. Heaps of vintage coloured sets these days. Smile

I'll correct the record this weekend when I am doing system maintenance.

Suggest this thread be moved to the Vintage Television forum.

What a wonderful selling point for a new colour television, it's going to break and need to be repaired! But at least it can be fixed quickly.

Should've put his brand on an Asian TV, like other British company (Rank) did, if he wanted to survive.

Here are a couple of photos of the various PCB's used in the TV. There are four main panels:
Horizontal Scan / Power Supply
Convergence / Vertical Scan
Chroma
IF / Sound
The small fifth PCB is the rectifier for the power supply.

There was an editorial in E.A. around 1969 advocating "Modules for (future) Colour Televisions". It's a seductive idea, but would it work in practice?

I wonder if anyone ever paid for an exchange Tyne "module" or just fixed the board. No doubt Mr Tyne was counting on a tidy revenue stream from modules. Did techs ever buy those small modules in "I.F. cans" in Philips K series?

Modular servicing has its place, & is far from new. I serviced a 1929 Series 70 Lyric Radio (USA). In those days servicing & parts supply was in its infancy. The most likely areas to fail were obviously considered to be the transformer & the capacitors, the bulk of which were in a large can.

Both the transformer and that capacitor bank plugged into the single Bakelite board that also had all of the valve sockets formed in it. As easy a changing a valve. Remove two screws swap them over, replace screws.

In Mr Tynes case I can see a strategy, people do not want their TV out of action for long periods. If a company authorised person can pop in & fix it in minutes, that is good for business. That can apply to equipment, like signalling.

One mistake, I see, is to have a repaired module sitting for ages unused. It can deteriorate & may fail when returned to service. If Tyne used one or two sets with modules, They could afford a dedicated setup with techs & equipment to test, repair & reset the boards & check the rental sets before they were sent to a new customer.

Reliability is how many Japanese manufacturers got market share. They "Burn tested" sets before they left the factory, so the real duds fell over before they got to the customers, problems were eliminated and the customers only saw reliable sets. I had an abt 1976 colour TV that was still going untouched in 2012, when it was passed onto a collector.

For those who may be interested, here are the circuit diagrams for the Tyne TV. The diagram is modular like the TV so it's a bit annoying to try and follow the connections from each page. The interconnection diagram helps to join all the bits together.

There are six main sections:

Tyne Receiver Circuit Diagram
Tyne Convergence Circuit Diagram
Tyne Decoder Circuit Diagram
Tyne Interconnection Circuit Diagram
Tyne Line Output Circuit Diagram
Tyne Scan Power Circuit Diagram
