Hi Peter,
well as Fernseh points out obviously not Bush, but then again Bush must get some credit as most of the design is lifted from the pre-war Baird T18. The timebase has seen the simple change from B5 Cossor 41MP output triodes to Mazda octal PEN46 pentodes which are triode connected. Similar changes are found elsewhere in the set, but the design is really the television part of a T18 with updated valves. The only new parts of the design are the RF stages.
Anyway, I have no clue as to who updated the design and re-designed the sound and vision RF stages.
I've included a picture of the scanning yoke from the T18 so you can compare it with the photo in my last post. I should measure the coil resistance values and check them against the T18 manual.
Cheers
Andy
