Default Re: Ferguson 705T Picture Request

Hello Mike,
I think you are getting mixed up with the 'Automatic' Pye range. They did indeed have the slotted turn things.
The Ferguson 705T had a circular disc at the rear of the receiver, customer accessible, with white plastic knobs that acted as fine tuners as well as programme stops. Thorn continued with this system well into the dual standard era with motor versions of the 850/900/950 series exclusively for their rental outlets.
As David has stated the double deck Thorn chassis first appeared late in 1958 under the Marconi VT161 banner. Pictures can be seen on a recent thread that I posted on the restoration of one of these fine receivers.
In 1959 Thorn released the first 110 degree model, the 500 series an example of the chassis I have attached. This is the TV/FM version the 516T. Printed circuits are used.
In 1960/61 the fantastic 600 series appeared. The picture shows the 'Golden Glide' 606T but large screen versions were available together with a transportable and a very early 19" model.
1961/62 saw the introduction of the 700 series. Almost identical to the 600 but employing squared off 19" and 23" picture tubes.
1963 presented us with the first and only dual standard chassis using the double deck principle, the 800/850. The difficulty with dual standard switching with two separate chassis saw the introduction of the 'flat' 900 chassis thus ending the 'Double Decker'. All of these Thorn or better known 'BRC' chassis were excellent performers and very easy to repair. The early dual standard had it's problems but so did they all! Regards, John.
