I believe that one Ferguson model 743T "Transvista" is known to exist in the UK. The line output stage of the 743T differs from the Pye TT1 in having one output transistor, a Mullard N7D, later to become the AU101. The TT1 uses two 2G221 transistors. I notice that the Ferguson uses an OC170 for the video amplifier.
Certainly the Ferguson looks a better product compared with the Pye which has a "prototype" look about it.
