I've attached three pics of the set. It has a 24 inch tube. The back is made of peg board. The well made metal chassis is shown from both sides. Accessibility to the component side when the set is running is not as good as you might think because the shortness of the EHT and scan coil leads prevent it opening very far- all of them unplug to open the chassis further. The unshielded Lopt and valves bottom right are just waiting to get you as you peer round the back of the chassis. Up on the top right the three valves are a 30C1, and ECC82 and a PCL805. The pentode of the 30C1 is the sync separator. The rest between them are the line and frame oscillators and frame output. Line output is a PL36. The transistor tuner is fed by its own little mains transformer and regulator.
I haven't done much on this set yet. The good contrast I had initially has faded to a somewhat anaemic washed out picture. Did this IF strip originally get an extra stage of gain via the VHF tuner?

" Did this IF strip originally get an extra stage of gain via the VHF tuner? " According to the information in the 1963/64 Radio and Television servicing book the Sobell ST282 series of models with either rotary and push button tuners had an UHF position. The mixer valve functioned as an IF amplifier on UHF.

Very neat chassis, looks to be finished in Murphy blue
I wonder how many still exist?
