Default Re: Ferguson 247T: huge console TV set.

All this effort is at last showing encouraging results. The CRT is excellent, as long as the heater remains intact and doesn't go partially short circuit there's plenty life left in it. The scan coil leads will have be reversed.
The picture appears too wide, that's because the width control is stuck in the minimum position so for the time being it has been bypassed.
For the frame output valve I'm using a Mazda 30PL1 in place of the PCL83.
Interlacing is good, Ferguson have taken extra efforts to ensure this by employing an ECL80 as the frame pulse clipper and shaper.
That complex gated AGC system is really good, much better than any mean level system.
So just a few minor jobs to do and this set will be the perfect big screen 405 line receiver.
