CTV Unusuall tv set

My best guess I would be a Tyne. I saw a couple of the earlier 90 degree delta gun sets. This looks like a later version possibly 100 degree delta? That's if Tyne made a later model? It looks like a similar layout and construction. Rich

Edit; Having looked again it may be 20AX. if that is the case too late to be a Tyne.  Could it be one of the Television magazine projects?

@michael-dranfield I not heard of the set, I have had a quick look at Television magazine from that era but found nothing.

I would have guessed Tyne too.

Likewise, when I first saw the photos last night my first thought was TYNE, the chassis frame looks virtually identical and also the use of a toroidal TX. However, the layout and circuit boards wildly different, I dismissed it. I hadn't considered there might have been other variations, and then there's the odd name MAM which threw me too.

The TYNE

I remember a company called MAM electronics, they were based in Lisburn, Northern Ireland. They were formed in the mid 1970's and made coloiur televisions aimed at the rental market and also cctv monitors. I think it was at the time when the goverment was creating jobs in Northern Ireland during "the troubles". I'm pretty sure I still have some service information somewhere. 

The set resembles the Berryvision which was marketed in the early eighties. Design of of the set was based on circuits in the Mullard application notes. The Tyne models were a development of the Berryviision set.

@crustytv Yes that is the Tyne model I remember Chris 90 degree delta gun tube built in the early to mid '70s during the 'colour boon' when demand exceeded supply. 

The colour boon sets were just coming to the end of service when I entered the trade in '77. The firm I worked for had all sorts out on rent which made stocking parts complex and expensive. We had Tyne, Finlux peacock, Saba hybrid and SS Telecommander, Emo. Teleton, National Panasonic, Korting hybrid and then we bought out a local firm that had loads of Thorn and Bush/Murphy sets out. Our mainstay was Pye. followed closely by SS ITT CVC20 etc.

They started to rationalise the rentals by 79 and the "oddball" sets were disposed of when they came back. 

I heard some of the bigger rental companies would dispose of any non-standard sets when they bought up a smaller company.  These could be a good buy for the smaller operators.

@richardfrommarple Yes I got some bargains when I worked there and after I left and started on my own.  They bought a couple of smaller dealers rental accounts and there was a load of Alba 3500 varicap sets, really clean and in lovely condition. They were disposed of on sight as they didn't want to stock the "special Thorn" parts. Then came a load of Murphy 823 varicap sets and a few early T20s. I bought them as well at a favourable price but they weren't quite as good as the Thorn sets. 

When I first went self employed I did some work for a place that bought direct loads from Granada. They got them working and then held one day sales up and down the country they were a real fly by night lot! But they paid good money and I could earn what had previously been a week's wages in 3 afternoons doing my own stuff in the mornings. When Granada had bought out another dealer the non Granada sets were cleared and were a doddle! I remeber a load of Tandberg sets all immaculate and very little to do to them that was a nice earner! In the lorry included was always some mono sets, they went straight into the rubbish compound... (or my van!) 

It's fortunate that some of the rental chains sold off sets to independents rather than scrapping them!

Later on they sold straight to the public, I remember shops would usually have an ex-rental section.  My Uncle managed to pick up some older but working sets this way for my Grandad or as a second set.

Yes, Remember the Granada "Cleaver Leopard's gone and changed it's spots!" Adverts? Directly putting down the independent second hand shops they had been selling to for years... Then OTV flogging off Thorn ex-rentals? They apparently were on first name terms with the trading standards people! It was a fairly rapid decline for rental after that.

Granada were buying up small firms to maintain their share, they bought all of my rental accounts I had in Nottingham. They just kept upping the offer until I accepted. They didn't want me being a fly in their ointment. I had a shop in the Victoria centre and they were a real PITA as landlords. Granada also went after my accounts in Peterborough, quite aggressively really, even trying to persuade my manager to convince me to sell. Within 5 or six years Granada changed to "Box clever" and the writing was on the wall...
